I tried several fixes, including hard resets, reinstallations and updates.
When I try to sync, it does connect to the phone, and says CONNECTED with the bluetooth icon on the watch. In the Garmin Connect Android app, however, it does not seem to identify the watch is connected and simply does not sync.
I am sure it is not a phone issue, since my Garmin 520 bike computer syncs within seconds of the ride and uploads flawlessly to the server.
Any thoughts?
