@ronwithmusic The response is incorrect. First of all, microG is not an OS and has nothing to do with this. Their app fully works on GrapheneOS and has no compatibility issues with it. The issue is that they're going out of the way to use the anti-competitive Play Integrity API to ban using anything other than an OS partnered with Google. Keep replying and keep filing issues. Users need to put a lot of pressure on them and burn lots of their resources. Can contact management on LinkedIn too.
