Last week I got 2 broken activities. When I finished a activity the synchronise logo appears in the upper part of the screen, but afterwards the fit file/activity is corrupt and not synchronised. I can find the activity in the activity historie on the watch, with some totals, but can load the activity on the watch. Upload the fit file manually on the garmin connect website isn't possible either because the fit file is corrupt. Does anybody else haves the same problems? I also have garmin explorer running on my phone.
