Thanks for the report @AlphaHasher. Which exact Nextcloud version do you use? I'm unable to reproduce this issue on latest Nextcloud 33.0.5.

@AlphaHasher thanks! I was only testing with mobile view (in developer tools) in a desktop browser, but not on a real smartphone. Seems like this issue is only reproducible when really using a mobile device.
