Never had a syncing problem until newest version and it's only happening on Garmin Express sync and not the old GC uploader nor GCM android app.
It seemed there was a corrupted file generated on my fenix2 that was producing a syncing issue so I was unable to upload via GCM app, so I connected it via PC and received "There was a problem communicating with the Garmin servers. Please try again later." I tried using the old GC uploader by deleting "modern" from url and sure enough it was stuck on the same file that was listed on GE, so I deleted the file from the fenix2 and disconnected.
Thereafter, it synced perfectly with the GCM app, but when I tried again with GE, it gave me the same error message but it came up with a different file time stamp which did not exist on the fenix2. Went ahead and deleted all files withing the "Activity" folder of my watch, and same error remained on GE, but not on old GC uploader nor the GCM app.
After rebooting both my laptop and fenix2, the error message remains on GE v3.2.13.0 "There was a problem communicating with the Garmin servers. Please try again later." and does not clear off despite the Activity folder being empty. How do I get GE to clear off this invalid error which wont go away?
