FaceTime Problem with ONE contact only
I am not able to establish a connection with only ONE contact in FaceTime. When I call, video or only audio doesn't matter, this contact receive the call and his FaceTime ring but after he accept the call is impossible to establish a connection. The same the he make the call: my FaceTime ring bat I am not able to establish a connection - start a conversation / video call.
Any idea?
Thanks!!
