Cant update my apps specially endless platform

@Andrea_Mercado it looks like you have flatpak runtimes installed from a “gnome” remote which you no longer have configured. Could you try this command in the terminal (please type it exactly):

flatpak uninstall org.gnome.Platform//3.22 org.gnome.Platform//3.28

If that succeeds you should be able to update your OS from 3.3.19

@tracy_pangilinan could you run this command in the Terminal and paste the output here:

flatpak update

If you copy your saved files to a USB stick, try reinstalling Endless with as many default choices as possible.
