Poor FaceTime connectivity
Getting consistently poor connection, Sydney/London. Picture freezes, drops out. Sound choppy, seems to be more so at London end (I am in Sydney). I have checked and consistently getting download speeds around 75Mbps, uploads 1.0+ Mbps. Has been thus for months. Not sure what London end using but they swear it only happens when talking to us.
iPad Wi-Fi, iOS 11.3, about 3 yrs old
