I've had the 910XT for about 2 years along with a Garmin Connect account. Never have had problems. I just came back from a run and didn't find my activity in Garmin Connect after the upload from the watch. The .FIT file is on my Mac and I have successfully uploaded it to Strava without any problems. Garmin Connect didn't upload it automatically and when I try a manual upload I almost immediately get the error "An error occurred with your upload. Please try again". I also tried to upload the corresponding .tcx file and it also gave the same error. Again, I repeat, Strava had no problem with this file, but GC cannot handle it.
I've included the .FIT file.
Hello Garmin.. any solutions?
