Yesterday's activity went completely ignored during sync. I did the exact same activity today and it uploaded. For whatever reason the Garmin Express/Connect system just doesn't recognize this activity as new, even though it shows up in the watches history.
I don't have the old ANT agent/Communicator in this computer. So I can't go to Classic mode and upload it individually. I tried and it locks while looking for activities.
I pulled out an old Mac that I haven't used for a year, which still had the ANT agent in it. I downloaded the communicator and tried it there. I didn't show one activity newer than 8/2013. That could be the last time I used that computer to sync with that watch. But for whatever reason, it says it recognizes the 910 yet doesn't seem to query it at all.
This isn't the first time this has happened, and it isn't consistent enough to track why it happens, but I've never been able to add those activities. Any thoughts on how to get an activity from my watch into Connect?
