Syncing problems between iOS, Android, Web - Duplicated and missing items
Issue: Web and Android versions (partially) out-of-sync with iOS version; tasks and projects unexpectedly duplicated; attempt to delete duplicate tasks unexpectedly deleted other non-duplicate tasks, resulting in permanent loss of several new tasks.
I added/edited/reorganized a number of tasks and projects via the iOS app while offline two days ago. Checking my tasks via the Android app and then iOS app this morning, I found many (though not all) of the projects and tasks I had created or edited on Friday were duplicated (in both Android and iOS apps). In one case there were two versions of the same new project, one showing 3 tasks (the correct number), one only showing 1 task (missing 2). I also found that the Android app was partially out-of-sync with the iOS app - several of the tasks I created via the iOS app (and which show in the iOS app) were not showing in the Android app, though other new or edited tasks and projects were showing properly via Android. Re-syncing the apps and restarting the devices did not resolve the duplicates or the missing tasks.
I then manually deleted the duplicate tasks and projects (carefully deleting only the exact duplicates) via the iOS app, and in several instances found that deleting one of the duplicates actually deleted a different, non-duplicated task. Deleting the duplicate project with the incorrect number of tasks (1 instead of 3) had the unintended effect of deleting the other two tasks in the other version of the same project. The deleted tasks and projects disappeared from both iOS and Android app display.
I then went to check the web version (via Chrome browser), and found that it was out-of-sync with the iOS app version, largely though not entirely in sync with the Android app version. The various tasks shown in iOS that are missing from Android are also missing from the web version, however the web version LHS project list shows 1 task in the "Next" project, though no tasks are actually listed under "Next" and neither the iOS or Android apps list any tasks under "Next" in the Project or Tasks lists.
End result: Android/web versions not in sync with iOS app, multiple tasks disappeared from all versions.
Desire: Get Android/web/iOS versions fully in sync, recover deleted tasks.
Note: I am not a Premium customer, so do not have access to backups to retrieve the tasks that were erroneously deleted. At this rate I may never become one....
