FaceTime between my Iphone and my kid's Ipad
Hello, I used to be able to "call myself" from my cell and it would ring on my computer and my son's Ipad. I just changed Iphone (from X to 11) and it's no longer working. FaceTime is working with others but not between our devices. It just says 'FaceTime unavailable" and drops the call. Any idea? Thank you.
iPhone 11, iOS 15
