facetime unavailable
I have an Iphone 8, 13, and newer Ipad. I am no longer able to facetime between devices. For example, I might be trying to facetime between the Iphone 8 and 13. The caller receives a message which provides "facetime unavailable" and the receiver receives a message "facetime failed". All devices are using the same IOS version. I never had a problem until a few weeks ago. I have done all the steps I can find online and on Apple but no luck. Any advice would be appreciated. Thanks, Red901
