Since upgrading to iOS 10 and macOS 10.12 at about the same time, I can no longer handoff calls from my iPhone to my Mac.
When a call comes in I get the notification window appearing on my Mac, as before. When I click the "answer" (or whatever it is) button, it pauses for a moment, gives an error message, and then the iPhone disconnects the call.
BT is turned on on both devices, both are connected to the same WiFi, Handoff is turned on on both machines. Any ideas?
