My Apple Watch is not receiving calls. The reason I took it out monthly was that I could be away from my phone and still receive calls via my watch. Also if I am in the house and my watch is in a different room I still cannot receive calls via watch. Occasionally my watch will let me know that there is a call coming through but when I answer it will say call failed. This is very disappointing and has deteriorated over time. I would appreciate a prompt response. Many thanks
