Hi,
First month was smooth. Now it does not even disconnect, but unpairs!
So the only way to reconnect it, is opening settings from the watch, clicking pair, insert the PIN and manually pair from Connect...pretty long procedure for a 24/7 tracker!
I've read a lot of problems on this forum too of disconnects, ended activities in the middle of the race; I've had same problem i've read here, bike race ended randomly on top of last climb...but there was still the downhill not tracked :)
Looks like the firmware/connectivity is very poor more than the bluetooth ittself, GARMIN are you going to release a decent firmware please? :)
