The Android widget is showing completed tasks with a line through them and they remain visible. They do not zhow in the app using the same view next 7 days.
To confirm, this is not a task that is a sub-task, as this would of course stay like this until the parent task was completed.
There is a known issue that we have yet to be able to reproduce where a task does stay crossed out for a bit, but it does eventually get removed. Please try signing out and back in again.
It is not a sub-task.
I have found that if I complete the task in the widget it goes away in both the widget and the app. If I complete it in the app it shows in the widget and the app with the line thru it.
Please try removing the widget, and then clearing the data for the App, and then log back in, add the widget. Let me know if it continues to do so.
I had the same problem where 2 tasks (one was a sub-task and one was not) were crossed out but still showing in both the Android app and in the widget, but not on the website. The tasks were completed 3 and 4 days ago.
I tried "uncompleting" them and then completing them again from inside the app, but the problem stayed the same.
When I did "uncomplete" and then complete again on 1 of them from the widget, both of them finally disappeared!
I don't remember how I originally completed them - widget, notification bar, or inside the app - but I know it was on Android.
Thank you for your report, our developers are looking into this issue right now.
Maybe this could help. I just recreated the problem once again. Like this:
1. Add a task with a reminder
2. When the reminder pops up, complete the task from the notification bar in Android.
3. After a few seconds the widget will update and show the completed task crossed-out.
4. Using the widget; uncomplete the task och complete it again - it disappears
