I've had watch for about 3 weeks now, and a couple of days ago I've noticed an issue with the Bluetooth connection. Every few hours, the watch will disconnect from Bluetooth and my iPhone also loses its wifi connection. On the iPhone, I can neither connect to the apple watch or a wifi network when this happens. I've tried resetting network settings and this hasn't helped. It seems like the only fix is to turn off Bluetooth and turn it back on, however, this is becoming very annoying. When I cycle the Bluetooth on/off on the iPhone, it reconnects both to wifi and the apple watch. Has anyone else come across this issue??
