Just received my apple watch, paired fine and all notifications, alerts and communication to the phone have worked great except for calls received and initiated from the watch. I didn't get the watch to use as a phone but wanted the ability to answer a call or start one to then handoff or send to my iphone. When a call is started or answered form the watch my iPhone 6+ becomes unresponsive until the call is stopped. No taps, button presses or otherwise do anything but display the apple logo. I have called apple and they have elevated the issue and are supposed to get back to me in 48 hrs or so. Have tried with no success: -handoff enabled and disabled with no difference -Unpairing and restoring watch and restoring phone and repairing watch -Forgetting all other bluetooth pairings on watch and phone -Apple ran diagnostic over air and said phone and watch looked fine.
