Apple watch Walkie Talkie stuck on Inviting
My wife and I both have series 3 Apple Watches. iOS 5 on both. Our phones both have iOS 12. We both have Facetime, and Facetime is connected to our phone numbers, not our Apple IDs. We can make Facetime calls. However, when we try to invite each other it's just stuck on Inviting. I restarted both our watches and phones, nothing. Why?
