Unable to list devices in a group on mobile web view and app

I’m using a local installation of phoscon version 2.23.02
Since a couple of versions the mobile view of the web interface and the Android mobile app both list the groups on the main page after logging in but it’s impossible to list individual devices inside each group. Clicking / tapping on the group name has no effect.

It works correctly using a desktop browser or using the desktop mode on mobile.
