I recently switched to CachyOS from Linux Mint. Maybe I’m missing something but, when installing Flatpak applications from the Discover application they don’t show up in the menus and I can’t add them to the task manager.
But after running:
flatpak update
flatpak remote-add –if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo
and a after a quick restart, they were all there in the menus.
Just leaving this here in case someone else runs into the same issue, or I forget about it in the future.
