after latest update cannot receive incoming calls unless from contact list
I have an IPhone 12. Latest update to 16.3.1. I only receive incoming calls from people on my contact list. The only exception is if I initiate a call and they call me back. Otherwise, the person says the call goes straight to voice mail yet I have no record of it. Very frustrating. Apple support via phone and screen share says all is well. Can someone help? Thanks.
