Because Revolut Ltd refuses to support highly secured phones with GrapheneOs, they force users to significantly increase their risk by using some old phones with an outdated non-maintained security-at-risk Android phone. Revolut app is so poorly secured than it is not able to detect any of these problems.
Conclusion: I have opened an account in another bank two days ago, and bye bye Revolut as soon as I get my new card.
