Same problem here. Xcode says running for minutes, although it is clearly not. Even if you turn off the Apple Watch, it is still running...

I have the same problem and is trying the "back and forth" method of using the iPhone. I suggest you disable this feature on the watch when the iPhone is not reachable.

Same problem. Whenever it is working, and I then have to disconnect my phone and come back the next day and reconnect it, it stops working.
