Flatpak -- Can't install from flathub

I get the following error when installing the Anki flatpak from flathub

All other flathub flatpaks install cleanly, so this isn’t an issue with my repo config.

Please contact the maintainer.

The flathub package is not made officialy by Damien, so this isn’t the right place to ask for support.

That being said, I just tried it and it installed just fine.
