Any way to restore or fast reinstall an installed flatpak?

[Alexander Larsson]

Yeah, but you don't have to re-download them, just re-deploy them from
the local ostree repo.
So, something like
 flatpak install --reinstall --no-pull org.gnome.Platform//3.28 ...
should work.

And btw, thanks for your patience with this, clearly it is possible to
understand and fix this, even if its kind of low-level, but we really
should have some built in tool that combines all these fixes to just
auto-fix-up your repo.
