My 310XT will not transfer my workouts via Garmin Express. The workaround (that is driving me crazy) is to remove the device from Garmin Express (but use the option to keep it on Garmin Connect). Then in Express click Add New Device. The 310XT gets picked up and my workout gets transferred to Garmin Connect.
Why do I need to Delete & then Add the device every time in order to get a workout uploaded?
