And it keeps happening all the time randomly with some files. Today I had an bike activity lasting over 9 hours with bunch of data and now I can't get it to the Garmin Connect. Sync with Garmin Express gave weird results - I got one file which had 0.00 km and then the sync just stopped at some point (with that green bar still there). I closed Garmin Express and tried to do the manual upload with Garmin Connect but it keeps stuck at the beginning when I select "Upload all new activites". Why is Garmin software so buggy and customer support so poor?
Is there any way to get the data from the watch (Forerunner 910XT, I forgot to mention before)? Data is there, I can see all the information but can't get it to sync...
Really angry at Garmin and their ignorant behaviour, why aren't there any answers on this forum from their support?
