This seems like a bug. I think something changed in the way they are checking the URIs on desktop. I have no trouble on my phone autofilling but on desktop (MacOS, Safari) I will launch the site from the saved URI and it will complain that the URIs do not match even though they do.
So it seems the reason none of the autofills are showing is because Bitwarden can’t find any matching URIs in this latest update.
