FaceTime failing to connect after trip abroad
Having used various networks, private and public, to access the web while abroad two weeks ago, after returning home I find FaceTime on my iPhone not working as before. It seems to say “connecting” while someone is trying to call me without success. I tried a number of things like “Reset Network Settings”, removing the FaceTime App and reinstating it, turning the App on and off, turning my network connection off and on and rebooting my iPhone after each of these steps without success. It seems that FaceTime would work for a short while after resetting my network settings then it reverts back to failing to connect. Any idea what’s going on and how it can be resolved. Thanks
iPhone 11, iOS 16
