Describe the bug

Everytime I attempt to use the application, it throws a constant synchronization error. This has been happening for months, with every version of the application. Issue persists after fully reinstalling nextcloud and notes on phone, including wiping all the data as described In the FAQ. Some things will sync despite throwing the error, like content changes; other things like deletes fail.

To Reproduce Steps to reproduce the behavior:

1. Install. Connect account.
2. Open Notes.
3. Error.

Expected behavior

The Notes app syncs with the server without failing.

Can youbplease check your server logs after this error appeared? Is there any hint?

Similar issue since last nextcloud android app update v3.23.0 (01/12/22). Might not be compatible with nextcloud notes android app ? I downgraded nextcloud android app to v3.22.3 and it works now. (reason why i haven't logs)

[lindsayschm]

well. hell. i finally got a chance to go look at my logs. i'm not so sure this has to do with this application in particular now.

i've actually been getting emails from my system about this but didn't realize what it was telling me... now i do.

ideas?

(edit note: i did go into my server and reinstall notes. tried again, nothing changed. still throwing the same error.)

@korelstar any idea?

[lindsayschm]

In a strange turn of events, this issue seems to have resolved itself. I double checked, and no systems have changed versions. The only thing that has changed is that i went in yesterday on another system and updated a bunch of notes and then deleted a bunch. The only thing I can think is that maybe one of the notes I deleted was malformed in such a way that it was breaking things.

Marking this tentatively as closed because the problem has gone away, and hoping I don't have to reopen it. Thank y'all for your time.

[stefan-niedermann]

Thanks for the update, feel free to reopen in case it occurs again of course.
