I have MicroG and almost all Android apps needed for my daily usage. Couple of special apps do not work. Specially one Finnish app meant for bird identification and that is because I have not been able to get location to work in Android apps.
Another problem is described here Cannot select a seat on Vr matkalla app
I have spare Android and noticing the need to use that is reducing every day. The most critical is when you have to verify to Google your identity. That is not working with my Jolla C2.
