Facetime not showing video of caller
My wife and I have identical iPhone SE, gen2 2020. Latest iOS, iOS 16.1.2, same settings (as far as I can determine), when people call her on FaceTime, or she calls out using FaceTime app she does not receive the other person's video feed, it only shows up with the initials of the person calling (or being called). They can see her video, she can not see their's. If she shuts her phone off and then turns it on again, it works OK for a few calls, then it goes back to no video.
If she initiates the call from the address book, rather than the FaceTime app she gets the video.
I have logged her out, logged in again, logged her out, deleted the app from the phone, restarted the phone - downloaded the app, signed her in and the issue persists.
I have no trouble with mine.
Any solutions would be greatly appreciated.
