Facetime incoming calls are not going through when my iPhone is LOCKED
After troubleshooting wifi/data connections with Apple support, third party communication apps are already working - meaning I can receive calls while my phone is LOCKED. However, incoming calls through facetime are not going through or my phone is not ringing. So I think we can isolate the issue on the facetime itself. Wifi and third party apps are already in good condition. Can anyone help me with this facetime issue? thank you
