im using EOS 3.5.7.
After doing a little more research, it seems that it’s probably related to a upstream problem. In the build configuration for the flatpak there is no “–filesystem=home” (save/load programs, …) or “–persist=.gnome2” (save configuration) specified.
As a workaround until the bug gets fixed upstream, you can manually override the permissions for GNOME Genius:
Only allow to save the configuration:
flatpak --user override --persist=.gnome2 org.gnome.Genius
or, allow full access to your Home directory:
flatpak --user override --filesystem=home org.gnome.Genius
