krysor 10.56.2 just got released. Still no difference?
Still no dice.
On the note of contacting Revolut, it appears that their Play Store responses are quickly dismissing reports which solely complain that the app is blocking custom Android OSs. Reports which describe GrapheneOS are getting actual engagement, in the sense that they want to contact the reporter and open a ticket. So it's desirable if people describe to them why the message about the OS being blocked for safety reasons should not apply to GrapheneOS because of its considerable security features compared to other Android OSs out there. I suspect that Revolut support has been instructed to simply reject reports that complain about "custom OSs" being blocked, while regarding GrapheneOS they might be more unclear on whether the blocking is a mistake or not, so they're actually forwarding our feedback to the developers.
I actually think using the term "custom OS" is not even correct in the context, so I don't think we are hiding anything by not using the term: simply being an alternative OS to larger Android-based OSs does not make it more "custom" than, say, Google's stock PixelOS.
A review where Revolut dismisses a report, and reveals that the blocking is due to trying to fulfill some certification:
I love revolut and been a customer for 5-6 years. But all of the sudden, they decided to stop letting custom Android OS users use the app. This means not being able to use this bank, as everything relies exclusively on this app. I hope they change their mind about this, because it's not helping anyone, specially loyal customers.
Revolut response:
We understand that this decision is not ideal and that it affected some of our customers. However, to certify our security protocols and that our app functions as intended we had to take this difficult decision. We sorry this affected you and understand your decision not use our services through the currently supported OSs.
