Apparently it affects most Garmin watches and not just Fenix. The fix, supposedly, is to delete all activities from your watch. I tried that and it worked for me.
The theory is that if you've had your Garmin for a while, the memory will be constantly near full and its the act of syncing that deletes old activities to make sure you have enough space for a new one. The Garmin outage apparently has disrupted that memory management.

Worth a try. As I said, worked for me.
