I've activated automatic updates in Gnome Software Center. Now more and more updates are shown to me here. Even after a reboot, the update notifications are still there.
If I manually click on "update all" and reboot, the update notifications disappear, but I actually thought, after reading the documentation, that updates would require no action from me at all, and that's what I want.
The weird thing is, the installed programs themselves claim to already be on the new, updated version.
So why are the updates still shown in the Software Center?
Distributing software is not instantaneous. Assuming that Mozilla has already sent the update to flathub, it will take some time before it's validated and available for download.
If instead of flatpak you had used native packages, you would be in the same situation, as fedora's update system keeps updates in testing until enough people say it's fine.
If you wanted to get the update as soon as possible, you would have to download the prebuilt binary from Mozilla, but then you would have to update manually and everything.
Just be patient for a few days.
I think they are asking, why it shows it needs to update even though they already have the updated versions.
But it's already up to date. It shows updates to the version they're already using.
Maybe look at the post before responding haughtily?
