I know this is really strange, but I can only point it out to the new iPhone’s (8 Plus and X) that my wife and I got. Whenever we attempt or receive a FaceTime Video, we can see the other person just fine...but they cannot see us or we’re frozen. This only happens when connected to Wi-Fi (at our house) but our old iPhones worked perfectly on our Wi-Fi for the past 3 years. The other strange this is after 2-3 FaceTime video attempts, everything resolves itself and works perfectly. Part of me wants to blame the Wi-Fi, but we have 100/100 internet and it worked perfectly before the new iPhones. Is anyone else having issues on a Wi-Fi?
