Nextcloud crashed on logging in

[falkgeist]

Steps to reproduce

1. I logged out of a previously added user
2. I logged in and was asked to grant access
3. After granting access the error message below appears
4. After opening the app again (not force stopped), I can see my files as expected.

Expected behaviour

I see my files (directly)

Actual behaviour

I see the error, before seeing my files (after closing and reopening the app)

It might be, that this is an issue with my server, but since I just updated to 21 and solved as many issues (had no critical ones) as possible on the server, I am getting the feeling, that the app is not working very stable for me. Also, uploads and sync is weird sometimes, either taking very long or showing a 100% sync as notification, that is almost to get rid of (only when force stopping).

Duplicate of #8370

I'm sorry, I don't see how to fix this problem for me from reading the other issue. can you please help me to figure out what to do to get this resolved? I am not so much bugged about the crash itself, but more about the failing uploads and the repeated appearance of the persistent notification.

[AndyScherzinger]

You can't workaround it since the ,matter isn't fixed but this is a "duplicate report of the same issue", so best follow: nextcloud/android-library#638 and wait for it to be merged/closed and assigned to a (future) release.

ah, sorry just skimmed for a solution, if only a workaround, must've skipped the "open" blindly as well. my bad, thanks!
