they are just saying that if you update your system packages, update your flatpak packages too. It’s all distro dependent in regard to how you achieve that. I personally use topgrade in my terminal, and it runs all the update commands (pacman, aur, fwupd, flatpak, gnome shell extensions, vs code extensions) in order.

When I tried this, it just gave me a vague error code when trying to log in.
