Did the trick

Thank you both for you help (:

I got 15 apps using this, does this mean I have to uninstall all of them? Holy… Even preinstalled (Fedora 40 KDE) once like kiview are listed.

Also shows me these apps as using org.gtk.GTk3theme.Breeze-Dark branch 3.22when $ flatpak update

I use “software” (gnome) to install flatpaks with an UI for now. I hope they fix the bug in discover sooner or later.

I have no idea other than just to wait…

Could you explain how? i tried uninstalling it, but I still got the problem in discover and it will reinstall on each update somehow.
