Synchronization failed

[DavidNorell]

This issue respects the following points:

• I have read the FAQ
• I have searched for existing issues
• The issue affects the Notes Android app, neither the Notes server app nor the Nextcloud Android app.

Describe the bug

My nextcloud notes app has difficulties synchronizing with my nextcloud instance.

I get "Synchronization failed" message 5 seconds after opening the app. The synchronization is mostly one way, i.e. I can succesfully sync from the nextcloud app to the nextcloud notes app but not the other way around.

Expected behavior

No error message and my notes always being synchronized.
