2. Set Classic sync ain Settings and try to unset some folders to not sync
3. No checkbox is visible anywhere near folder names

Folders in Classic sync in Settings must have visible check boxes.

Screenshot how the Nextcloud settings window appears after trying setting it to light theme. (Did not help. Other apps are in dark theme, it was the same just dark window.)
