This has happened a couple of times now. I tried to search for it, but had no luck, so apologies if it's been addressed already.
On Thursday, I used my Garmin 910XT for a run workout. I then held down the mode button to reset it and powered it off. Or perhaps I powered it off, and then reset it the next time I powered it on. Not sure.
On Sunday, the next time I powered it on, I used my 910XT for a bike ride. Afterwards, I hit reset, I then plugged in the ANT stick to upload the data. First attempt failed and shut down the 910XT. Not unusual. That happens a lot. Powered the Garmin back on. It took over an hour for it to sync, and reported that it synced correctly, however there is nothing in Garmin Connect for either activity. I went in search of the FIT file, and found 116 FIT files uploaded for these two activities, ranging in size from 1KB to 115KB.
First, what can I do to get these activities into Garmin Connect? And second, what can I do to prevent this from happening? It never happened before the Garmin Express method of upload.
