My walkie talkie contact is “ unavailable “ when I know he’s available
I have a friend who is set up with the Apple Watch ultra walkie talkie. In the past it’s worked well. Now I can’t contact him ( it says he’s unavailable). I checked FaceTime on both of the iPhones and double checked the watch utilities settings for accessibility with “ tap to talk” set “ on”. We had it working after we shut bot watches down and both iPhones Now when I tried to reach him just now it says he’s “ unavailable “. Any suggestions?
iPhone 6, iOS 11
