Notification for recurring task re-appears after completion

[major-mayer]

I have two (daily) recurring tasks that I usually complete via the notification which i receive every day.
Most of the time it works well, but sometimes the notification just re-appears as if I haven't completed the task.
This is not only inconvenient, but if I complete the tasks another time, it actually completes the tasks for the next time.

In this screenshot, you can see that i have the two notifications for task A and B that are recurring on a daily basis (+ one irrelevant task).
It looks like both of them should be completed today and are open since 2 hours.

In fact, I have already completed one of those tasks, which you can see in the app.
Only task A is due today ("Heute"), task B is actually due tomorrow ("Morgen").

I am syncing my tasks to Nextcloud via Dav5x, if that is relevant, but completed them via the notifications of the Tasks app.

I think I've experienced this a few times before but have never been able to pin down a root cause.
Would it be possible to share a screenshot of your task to see how it is configured?

[major-mayer]

Yes of course, everything that helps to debug this issue.

The "pausiert bis 8. Mai 9:00" is only to get rid of the notification for the rest of the day.
Normally it's not paused.

Thanks for the details, and sorry for the trouble! I am hoping this is fixed in v13.9 - if you're interested in testing this out you can sign up for beta testing in the Google Play Store

[major-mayer]

All right, I've registered for the beta group, but not sure if I can really test it, because the error only occurred very infrequently.
If I encounter it again, I will tell you.

[major-mayer]

Unfortunately, I just got the same issue again on version 13.9.4

[abaker]

Can you see if you still experience this on 13.9.6?

[major-mayer]

So far I haven't had any issues.
I will report if it occurs again.

[major-mayer]

Jep just had the same issue again :/

[abaker]

Is this happening with only snoozed tasks or any task?

[major-mayer]

The notifications appears again immediately after I mark the task as done (using the notification as well).
The task is not snoozed at this point.
I only snooze it sometimes when I get annoyed about this second notification, but just for a few hours.

But actually the second, unwanted notification just disappeared again.
Don't ask me why, I was just checking the task details within the app and it disappeared 😅
So maybe this is partially fixed already?

[major-mayer]

But I see a difference now :
Before it was impossible to swipe away the duplicated notification, but no it is possible.

Another user that reported this to me a few weeks ago, and was experiencing it regularly, messaged me today that they haven't seen this since updating to 13.9.6.

I believe I fixed the original issue in one of the early 13.9 betas, but then refactored some notification code and introduced a new-but-similar bug. The new bug was specific to snoozed tasks, and is fixed according to a unit test.

Its possible there is yet another bug (the original bug is gone because most of that code is gone), so any additional patterns or details you can provide will be helpful

[major-mayer]

Okay good to know.
So what kind of details would you be interested in, if it happens again to me?

[abaker]

It can be hard for me to reproduce bugs because there are so many features and configuration options, but if you notice any patterns with the affected tasks, like recurring vs non-recurring, what notifications are configured for the task, if there are other notifications happening at the same time, etc, that can help me repro something so I can fix it.

The second snooze bug was triggered by snoozing a task until it would fire again at the same time as another notification for the same task, e.g. a task due at 9AM w/ a repeat notification every 24 hours, snoozing the task until 9AM caused double notifications. I rarely snooze tasks and don't use overdue notifications, so I was only able to find the bug thanks to a user report

[githubtefo]

Not sure if related, but for repeated tasks I am not having notifications at all (I do see the notification on my desktop for the same tasks in GNOME).

[major-mayer]

Didn't experience this issue any more in the past months despite using it daily.
So I guess this is resolved now.
Thank you :)
