I've had no real issues with the watch connecting in all the time I've had it, other than occasionally needing to be patient when it was a bit slow to "latch on" properly. However this morning I needed to update the quick GPS but couldn't get the watch to connect at all. Tried to "find" the watch through the bluetooth section in settings on the phone- no joy. I tried switching everything off and back on. "Forgot" the watch and tried to reinstall it. No joy. Plugged the watch in to do a soft reset. No joy. I can still download data by plugging into my mac, and can update the quick GPS this way, but the bluetooth connectivity was just so useful.
I'd be very grateful if anyone has any ideas.
