I have same problem running 2 weeks now. I get alerts so I know bluetooth is working. I've tried removing the watch device, tuned off the watch, turned off the phone, turned them both on, reestablished the bluetooth, and tried to synch but it doesn't work. Trying to initiate a synch from my phone, the watch seems to start trying to download for a while, then just stops. A couple of times I got an error message about it appearing busy ("Your device seems to be busy, and your synch request timed out. Try again later"). I was not able to get any GPS tracks from it. Trying to initiate a synch from the watch in different ways, I eventually got an error message that the synch was already in progress. I powered off the watch again, and restarted it. The synch restarted automatically but again failed.
