My child is soon to be starting residential.school. He has his own ipad and I have mine but his is set up from.my ipad so we share the same account. I'm trying to set up a way for us to video call each other and failing. I'm useless at tech so if anyone can show me an idiot proof way to do this, I'd be grateful. I can't delete my settings off his ipad as he has some communication software shared from my ipad on his that needs to stay as it is used daily.
