I use several European banks, GrapheneOS works just fine.
FYI, I know that Revolut is a Europe-wide bank which does not use Play integrity. In case anyone needs it.
I've only had one non-banking app trigger the "used Play integrity" warning, though that app apparently does not care and still works fine.
ChatGPT app is annoyingly triggering it with every prompt reply.
But there is this escooter app in Norway called Ryde, that blocks itself from even being seen on Play Store. They are otherwise very good, excellent support, responded positively to some UI feature requests. They also have a living wage policy for their battery maintenance mechanics.
How would I approach them about changing how they verify phones? I'm no dev really and feel like it's a little above me.
I'm not sure that's the best answer but GrapheneOS has a page they recommend linking to developer that may be interested in supporting something else than Play Integrity: https://grapheneos.org/articles/attestation-compatibility-gu...
That's what I would ask for if I knew what I was asking for. Thanks!
