@razze If you have #gnomeos, can you please try adding the #flathub repo with the #floss subset using a #flatpakrepo file?
On fedora 42 with #gnomesoftware 48.3, it adds the entire unfiltered repo, while adding it on the command line works.
The point is to create an easy way for nontechies to add flathub-floss by just opening a flatpakrepo file in gnome software, without using the terminal.
