I'm using a Garmin Forerunner 310xt and an ANT stick. Garmin Express tells me it's loaded my last two activities, and the data is recorded accurately on the Garmin itself, but it's not showing up on Garmin Connect. The last time this happened there was a glitch on the GC website. Any clues?
There is a sub-forum for Garmin Express where actual Garmin reps answer posts. I might be better to post there as sync issues are likely due to a configuration issue with Garmin Express.
