Sometimes the sync happens automatically other times, I have to push every button, re pair, or wait. The watch (forerunner 220) will say it is connected, but the app, Garmin Connect will say not connected and there hasn't been an observable pattern as to why it syncs automatically sometimes and sometimes not. Any clues?
My Forerunner 220 does the same thing. Sometimes when running it connects and disconnects. Other times nothing. Many times I have to select the Setting Bluetooth on the watch and set it next to my phone after a run to make it update.
