Any progress? Currently, the app is useless to me / not functional at all.
I'd be happy to provide more information to solve this problem.

Nextcloud client app starts and probably asks for login credentials.

Is this a brand-new installation of the app?

[RealDiez]

No.

Though, not sure whether related:
The app worked without problem for years, then the SD card died (adopted storage). After inserting a new, blank SD card, I had to re-install the nextcloud app and re-setup everything. Then the app was working as expected.
After a reboot of the device, the trouble started.
I tried older versions of the nextcloud app (3.28) and the newest available version (3.29.1), without success. 3.29.1 doesn't even display the crash log, it just silently vanishes after the splash screen.
