I use Bitwarden (as far as I know these are basically the same) and have had issues with the app too, from long delays before it autofills, to the popup jumping around the screen or vanishing after 1ms, to just never showing up on some screens. I would recommend trying some of the other autofill options they provide in settings to see if they work better for you. I have had much more luck with “inline autofill” than the accessibility-based autofill, but currently keep them all enabled and the experience is much smoother than it was a year ago.
Apart from the key bind loss, which would be asinine to remove permanently, this looks like a straight upgrade. Better readability and more in line with the rest of the UI design.
