After syncing, in Garmin Connect I have wildly wrong actives--rides on dates I never rode, places I never rode. And many of my real activities are missing.
Any suggestions for this--I deleted all the bad activities, and I have a complete .tcx file of correct activities. Do I have to pick through my activities one by one, export each one, and upload it to Garmin Connect? What if I deleted my entire account and started over by importing my .tcx? Anyone tried this? It's also wreaking havoc with Strava.
