Looks like this is failing for lots of us regardless of device. I'm on a 620. Have to assume the problem is server related and not some weird time zone change software bug..
I too am having the same issue as I can't get my Vivofit to sync with my android. I tried unistalling the app and reinstalling the app and it get hung up with the following sync results:
Just adding that the issue is affecting me as well. Attempted syncing through Garmin Express, the Classic Upload function, and even directly uploading the .fit files. Nothing works. Hopefully there's a fix soon, or at least a better software to use.
