I ran flatpak list and found that I seem to have Fedora Platform org.fedoraproject.Platform 32 f32 fedora system installed instead of the f33.
I have tried googling, but found nothing of interest. flatpak update doesn’t seem to help, either.
This is the runtime for the fedora flatpak repo. I believe it was initially built for an immutable system like silverblue, but it also gives you access to flatpaks following fedora’s packaging guidelines, or just a simple way to get flatpaks without adding flathub. flatpak remote-delete fedora will remove it and any apps unstalled under it.
Nope,
Runtimes are like dependencies for packages. Flatpak Concepts
Flatpaks can have multiple versions of the runtimes installed depending on what the applications require.
To list applications that are used by a specific runtime: flatpak list --app --app-runtime <runtime>
for example: flatpak list --app --app-runtime org.gnome.Platform
To remove runtimes that are no longer used flatpak uninstall --unused
