Duplicate tasks

K

Like other people, I keep getting duplicates of tasks. It seems to happen randomly when I touch a task - I keep wondering if I'm doing some kind of special tap, but I'm not! It's very unhelpful as the duplicates need to be removed. I remove them, and it looks as though only the duplicate has gone, but shortly afterwards, sometimes they've BOTH gone. Disaster - I'm losing tasks before they're done! I see others have had same problem - are you near fixing it or do I have to live with duplicates in my list?! I'm only using it on iOS - latest iOS and latest Todoist. I've just recommended Todoist to family as otherwise I love it - I don't want to have to withdraw my recommendation!

Hi Kaye,

Have you indeed updated to the latest iOS app that was just recently released? As this issue should be resolved. That being said, try logging out of it and re-installing the app, even if it was just updated.

Hello Kaye,

We're sorry for the inconvenience, we're currently changing some sync processes in the iOS app and this should address this issue in next updates.

I'm still getting this problem too. I believe I've isolated it to happening when I'm adding items a/offline (eg in an airplane) or b/in a poor wifi or cellular service area. When I come back fully online, the first sync is clearly corrupt in some way and the new items are duplicated

I think it's getting worse - please fix ASAP. I just noticed it happen several times (I'm in Today view). The worst thing is that if I delete the "spare" version, only that one deletes, (so I think I'm safe) until a few seconds later when - possibly only sometimes - the other needed one disappears too. I can't keep using Todoist - however much Iove it after deciding on it after trying all other front runners- if you can't fix soon!

I'm in Africa. Was using iphone without Internet connection and did lots of updating of projects/tasks. Had brief Internet connection (wifi) and to my horror every new project and every new task was duplicated (and I seemed to have 3 copies rather than just 2!)

I disconnected and have sorted it all out again, but dreading it happening again when I connect to Internet back in London next week. Is it fixed yet?

Minor additional problem - I can use icons (smiley face etc) in project names on my iphone - which can be very helpful for quick visual recognition of projects in a list - but as soon as I connect to wifi they disappear and I get a garbled text term stove instead. fixable?

Yeah, for some reason, todoist just cannot get this sync thing figured out. Lots of effort, several new versions to attempt to fix the problem...but every time I pull out my phone in flight and start to do some work on my list...I hesitate...and I then...

...wait for it...

...wait for it...



...yup...I pull out an *actual* piece of paper, and *write* down my changes, then when I land and get connectivity again, I make the changes I wrote down in flight.

So, there you have it. That is how to fix the sync and task duplication problem while offline: Use a paper and pen/pencil. Lol! :'-(

Hello,

@Kaye - it should be fixed in the next release (coming most likely in a week, though it's subject to change due to Apple's approval process), but please note that the duplicates should be visual only so either logging out and back in after it happens or reinstalling the app should remove them.

@Stephen - the next version introduces some significant rewrites in the syncing process of the app, we hope it will finally address all sync-related issues.

I see this all the time too. I use Todoist on my Mac, my iPhone, and a Windows machine. Seems to be a sync related issue. I'll refile something on the Windows machine and go look in iOS and the items are in two places, or something.

I haven't tried to reproduce it absolutely but that seems to be the pattern, more or less.

This AM I deleted a duplicate on the iPhone and on the Mac the existing item is gone, but it still exists on the phone.

Pretty frustrating. I know sync is hard but ...

I'm not sure but it seems like some IDs are wrong or what.
As it is very hard to reproduce - it just happens on an odd day.

Just now on my iPhone I've got 2 twin tasks after syncing "Today" (didn't do this for 3 days). I tried to torture those a bit:
1. when I added 1 note to each twin from iPhone - they both have 1 note on iPhone, but the Web version of a task had 2 (so it has merged them).
2. When after that I've marked as done one of the twin - the Web one was removed, the iPhone had still a clone, which dissapeared after sync.

I guess I should mention at least what I did:

1 - Open the Todoist app on my iPhone 6 (opens to 7 day view)
2 - Hit + button to add new task
3 - Type in name of the task (in this case it was "Lock breaker box"
4 - Tap the date field and tap the "tomorrow" link that pops down
5 - Hit "Done"

I didn't change anything else when I was entering the task. Also, because this has been happening, I've been checking for duplicates as soon as I enter it, and I don't recall seeing a duplicate for this one until much later.

David Schlesinger premium

I'm still seeing this as well. My best guess is it happens when I add a task in an area of poor wifi/3G reception. I think what happens is part of the sync handshake gets lost. The duplication doesn't occur on any other platform but the one I am adding the task on AND, I think crucially, if I delete the task on another platform only one of the duplicates gets deleted and the one that remains is a stub unseen elsewhere. In other words
To do "test" added on iPhone
Iphone:

iPad:

Then if i delete it on the iPad, I get
Iphone:

This seems to be getting worse and worse with each update. It is happening much more frequently now. As Taco V pointed out, we keep being told that it is going to be fixed. Can we expect this to actually be addressed?

I rely on Todoist to keep all of my tasks, and if I can't trust it to adequately do so, I'm going to have to find a new program. I've been a huge Todoist proponent and convinced many friends and colleagues to begin using it. I'm now extremely disappointed with how the quality seems to be deteriorating.

I'd love to see a bit more honest of a response from Todoist staff rather than simply hearing "version X.X will fix this issue" when we have seen that this proves not to be true.

Nicholas Wilson premium
Replied on Oct 22, 2014 - 16:07 UTC

I had kind of a sidebar conversation with someone from Todoist about this when I renewed my subscription. It is definitely a tough spot for everybody. And as a software developer and support guy, I definitely understand the frustration on their end too.

The fact is though that you cannot reliably fix a bug unless you can reliably reproduce it. Now as far as who needs to figure out HOW to reproduce it and who should spend the time to do it is up in the air. It's sometimes frustrating hearing a support or dev person say "we can't reproduce this, let us know when it happens" because it almost seems like they're giving up and leaving the onus on the customer.

The best way though to get this fixed is for everybody to be very cognizant of the EXACT steps they're taking leading up to the issue. The next time you go to enter a task, note to yourself exactly what you did and how you went about it, as well as any unique variables that could be in play (for example, were you in an area of low cell data coverage? Was your wifi cutting out at the time? Were you just walking out the door when you entered this? What time of day was it?). If the issue happens, then write all of this down and post it here, step by step.

The best would be if someone starts to notice a pattern so that it can be reliably reproduced. I haven't been able to come up with anything, despite having a couple theories.

Some people on this thread are saying it's happening almost every time they enter a new task. Please go try again and write down everything as you're doing it and let the support/developers here know what you did to reproduce it.

Hello Ryan,

Every response we provide it honest. When we ask the developers when it will be fixed and they tell us that they still can't reproduce it, but found a part of code that theoretically might cause this and it will be changed in the next update, then all we can do is to inform you that this is the current status - they found something and it will be addressed.

In the past few months, the iOS devs have pretty much rewritten the whole syncing code and were certain that it's not possible that any data will duplicate in the new version. Unfortunately, it still does, but the worst part is that we're unable to reproduce this under any possible circumstance. All our devs need to be able to find the true source of this issue is a way to trigger it. Even once.

That said, right now, our next steps planned for fixing this issue (as the developers told us recently):
1. Keep asking everyone who reports it for every detail about the circumstances in which this happens. Anything that will help us trigger this on our end will be extremely helpful.
2. After the next upcoming update, if by then we still don't have a way to reproduce this, we'll rewrite the server-side syncing process so it will be more "aggressive" and reject synced data if it seems in any way to be duplicated.

The second step is something we wanted to avoid as it will affect all platforms and it's something we must be very careful with to make sure it won't incorrectly reject valid data. For now, it seems that this happens on the client side in the iOS app, but again - if we can't find any way to trigger this, we'll have no other choice as we do treat this very seriously, but at the same time we must look for the true source of the issue and not implement processes that will affect other platforms just as workarounds.

Ryan, if you say it keeps getting worse, do you see any pattern to it. Does it keep happening always when you're at a certain network, always on wifi, always on cellular, always offline, always when you add a task from one certain view, always when you reload the app... anything that can be repeated, this would help us fix it immediately.

Антон, you've said that is happens "almost" every time you add a new task. When exactly does it happen and when does it not happen? What's different about the situations when you add a new task and it duplicates and when you add it and it doesn't duplicate?

Omar, you've mentioned that it happens also on Chrome - can you reproduce this on Chrome after completely deleting our iOS app from your device so we can say for sure that there's no way that the iOS app is generating the duplicates and sends it to the web?

David

Thanks, David. As a developer, I, too, can sympathize with you. I can report that I have not had the duplicate issues since the last revision...I've tried to make it happen, but, frankly, its working just perfectly. I tried for almost 30 minutes on ipad, iphone, on an offline, all variations, then the desktop (windows version), and cannot get it to demonstrate the duplicate issue.

I travel a lot with this thing, and I use it on the aircraft all the time, offline, and with the latest versions, I've always had it sync perfectly upon landing and the resumption of 'net access.

Seems, to me, you've got this fixed.

Others that are having this problem may have other issues...and it will be virtually impossible to duplicate them. In addition, as will all software issues, virtually nobody will let you know when the thing is fixed...but they sure will tell you when it *isn't*...I'm just letting you know, I'm in the former camp.

Hi David,

I'm a software dev myself and clearly understand "steps to reproduce" importance.

Need to say that I suffered from this and wished to help but it isn't reproducible since last time I wrote (see above). So my case was probably fixed and I'm useless.

Nevertheless, I was NOT able to reproduce it even before it was fixed for me. And I believe I've a black belt on reproducibility. When it happened - there was no way to get it 2nd time in a row. That's why I think the pattern is in something we users cannot trigger by intention (e.g. collision of some IDs, or mistakenly expecting to receive http packets in a same order they are sent, etc). Bug seems to be very occasional.

In any case, we devs use to gather info by ourselves :) You may easily detect that 2 tasks with same name were added during 3 seconds (the case looks unreal enough) - and in that case - do gather/send *all* relevant info about tasks/user/environment for investigating: affected audience, frequency, patterns etc.

Let the force be with you.

I've had this same issue for several months. I'm currently running iOS 8.1 on an iPhone 6. I just logged out of my app, deleted the app, reinstalled, and logged back in and my duplicates were gone. I think the reason that deleting the duplicates sometimes deletes both items is when the item deleted is the original. Deleting the original deletes the mirrored item as well. If we delete the duplicate, the original remains.

I'm wondering if the issue isn't that items are actually being duplicated. If that were the case, I would expect those dupes to be sent back to the server on the next sync and then to show up on all platforms. It seems as though the issue is actually in the display of the data on the iOS client. The data is fine, but it's showing up as two items.

Nicholas Wilson premium

So I just had something that I thought was really strange and maybe breakthrough, but I think Mark beat me to it.

Anyway, the weird thing was that I had a task that had "duplicated" itself. One weird part was that the task was not showing up as duplicated before. I swear (though I don't have a screenshot) that it was just one item after I put it in. All of a sudden today, I looked and it was duplicated. Anyway, that's not the weird part...

The weird part is that I went in to delete one of them, and instead of choosing the top one of the two that were duplicated, I chose the bottom one. I tapped it, then tapped "edit" and chose "Delete Task". After doing this, it showed that one disappear from my "Today" view, and about a second later, the OTHER one disappeared!

This leads me to believe (like Mark said) that these aren't true duplicates, and that the iOS app is just displaying the same task twice for some reason. This could also explain why sometimes I swear a particular task wasn't duplicated when I entered it, and it gets duplicated only at a later point.

Hopefully this helps a bit.

Thanks,
Nick

David - Thanks for the response. I didn't mean to imply you guys are being dishonest... Poor word choice on my part. Sorry about that. I was just looking for a more thorough answer, and I appreciate the response you gave. I'm glad to see this is receiving attention to fix the issue.

Others - I appreciate the insight. As someone who is not a developer, it is probably too easy for me to think that bugs should just be fixed and not understand the complexity in doing so.

Here are a few details on my most recent instances of duplicate tasks that will hopefully be helpful. First of all, I'm running Todoist v.9.0.1, iOS v8.0, and Safari v8.0. Lately, I've only been using Todoist within Safari and iOS. This happens relatively infrequently given the total number of tasks I enter, but it does happen often enough that it is a problem.

Here are the details of the most recent instances:

Instance A:
1. I entered a task on my phone on Monday, scheduled for Tuesday. (I'll note that I've never noticed any correlation with particular projects, priorities, or reminders). I was on wifi at home when I entered the task and had good connection.
2. On Tuesday, I looked at my tasks for the day on my phone and the task noted above was listed twice. I pulled up Todoist in Safari, and the task was only listed once within Safari. I deleted both tasks and re-entered via Safari.

Instance B:
1. I entered a task on my phone on Saturday afternoon while using cellular data, but with a good connection. I originally scheduled this task for Monday.
2. On Monday, I rescheduled the task for Wednesday. I don't recall if I did this on my phone or within Safari.
3. On Tuesday, I rescheduled the task for next week using Safari. When I pulled up my today list on Wednesday morning using my phone, the task was still listed as a task for Wednesday. It is also in my phone as a task for next week. In Safari, it only shows the properly scheduled task for next week, not the duplicate today.

In both instances, the app badge count does not include the duplicate task.

I hope that helps.

Thank you very much for your reports, I'm passing them to the developers.

Okay, I have a bit more information. I was hoping that after logging out, uninstalling, reinstalling, and logging back in that I would be rid of the issue. Not yet.

But I do have some more information. I had a duplicate task show up today. I edited the TOP task and changes to that task did not affect the bottom task. The changes I made were adjusting the priority. When I made changes to what was originally the bottom task, those changes affected the duplicate. So one instance is indeed reliant on the other, but not the other way around. I think I'll go in and try some other changes.

More information. I tried making changes again, this time with labels. I labeled the TOP instance @duplicate. On the next sync, nothing happened to the bottom one. Then I changed the BOTTOM with a label @original. On the next sync, the top one lost the @duplicate label and was replaced with an @original label. Just to double check, I added the @duplicate label to the TOP one again. It now has both labels, and the bottom one only has the @original label.

I think that the natural thing for most of us to do is see a duplicate and try to delete or complete one of them to get it off the list. (It also counts toward the badge count, by the way.) Naturally, we think the second instance is the duplicate, so we get that one off our list. Unfortunately, the bottom one is actually the original, so when it gets deleted, so does the other one.

I believe that we can delete the TOP instance and not lose the whole task.

Excellent forensics Mark! ;-)

This time I tried changing the name of the task. Name changes didn't seem to roll out to the duplicate. I added "CHANGE" to the end of my bottom task name, thinking it would add that same text to the top instance. Nothing happened.

So I added "fixed" to the top instance. On sync, I still had two tasks with two different names. Changes in one did not affect the other.

UNTIL I changed the label on the bottom task. THEN it made the top task name the same. Now I'm back to two identical instances.

Wow. This is weird.

When I add a note to the TOP (duplicate) item, it stays there. When I add a note to the BOTTOM (original) item, it moves to the top item and doesn't stay on the bottom item. My top note now has three notes (one added directly and two via the bottom instance) and my bottom instance has no notes (even though I added two to that instance).

Reminders worked like notes. TOP stays as is. BOTTOM reminder gets moved to the TOP instance.

Holy cow - Todoist, you guys looking for a QA analyst??

PS, Mark (and everyone else) - I noticed an update was pushed out in the App Store yesterday afternoon. Did you download it?

Guys, this problem has been happening for me for a while now. I thought I could live with it, but I can't anymore. It is annoying as ^&#&$#(. As previous posts have indicated, you can't delete a duplicate task without both tasks being deleted.

Please fix this asap. This should be your top priority. I will not renew my membership if this is not fixed. In fact, I'm already looking at alternatives.

Here is what saw.

1) created a task on IOS
2) The next day I launched the app
3) The task was duplicated
4) I changed the due date
5) the duplicate went away.

Thanks Omar. That didn't work for me. I also shouldn't have to do that anyway. The main benefit of going premium was unlimited syncing (that should be accurate).

I was sitting in my local plasma donation center donating plasma. I was reading a printed article. Two times while reading it, I added tasks to remind me to send the article to two folks. Added both identically, on the same WiFi network. One produced a dupe; the other didn't.

Not to revive any old issues, but I haven't seen the bug for a long time now. Running 9.0.2. Can we be cautiously positive it has disappeared? Any updates from the dev team since the great bug reports?

Hi Taco,

We did fix issues that can cause duplication in our previous updates. Recently, we identified another bug that might have caused duplication of tasks and we're hoping to make it available in our next release.


Regards,
Clyde

I haven't had any issues since the v9.0.2 update either. Thanks for the continued attention.

I don't think I've seen it in a while either, possibly since that update. Hopefully that continues. Thanks guys.
