Yes. Revolut prevented new users to login in a specific version of their app (the newer). Users that were already logged in could update the app without issue and users could use an older APK of Revolut to sign in. However the PlayIntegrity process that was banning their GrapheneOS users have been resolved and now the harden OS is whitelisted from Revolut.

At least that’s what I have followed/understood from the whole thing but I am not a Revolut user.
