bluegrass Damned, that's a huge letdown and a showstopper for me, because unfortunately I just can't do without Revolut (personally and for business).
So they really don't want to allow their apps on GOS specifically, although the message has already been conveyed that it's the one and only custom operating system that's more secure than stock Android.
The question is now, is someone here that can investigate further what's the issue this time?
I am quite certain that this still has nothing to do with Play Integrity and I am still hopeful that this is not the end for Revolut on GOS. It may be a mouse and cat situation, but as long as it can be fixed somehow, well...
