Revolut recently banned using GrapheneOS without any justification. They're falsely claiming to do be doing it for security reasons. In reality, they're enforcing licensing Google Play. Revolut doesn't enforce security standards. It runs on Android 9 with no patches since 2018.
This is probably something you have to get used to when using Graphene unfortunately. Just pack up and leave, there are tons of banks where the app works fine.
