With a tool as Hermit (https://hermit.chimbori.com/) Revolut is still working. I use GrapheneOS on a Pixel 8.
We've added an initial section to our site with a list of apps explicitly banning using GrapheneOS via the Play Integrity API with links to their Play Store pages:
https://grapheneos.org/articles/attestation-compatibility-guide#apps-banning-grapheneos
We'll gradually expand this list to include many more apps and then we'll link it a lot.

Existing logins in the native app should still work fine, for now, but they might eventually block them too. Can confirm installing the app in a new Private Space, work profile or secondary user instead of logging out and losing access.
In my second profile (GrapheneOS on a Pixel 8) Revolut is indeed no longer reachable.
