A GrapheneOS developer (@[email protected]) points out that it seems like that’s due to Revolut using Play Integrity API incorrectly (from what I understand). If they were to update the app and actually use the result, it might lead to Revolut not working on GrapheneOS either.

With my complaint, I’d like to get Revolut to work on all degoogled phones and not have any risk of an update suddenly killing support.

It’s not empty to the submitter (me).

Must be some reddit bug or it works that way by design.
