Bradman117 Are using RCS/chat features in Messages? What carrier are you on? It seems I need GP Services in order to use RCS on Xfinity mobile.
Until I installed Play Services and Play Store, Messages said my device did not support RCS. Once Messages "verified" my device, I can revoke all permissions of GP Services and disable GP Store, and RCS still works. But once I disable GP Services, Messages complains immediately and disables RCS.
