As is my routine, I take off my watch (910XT) after an activity and put it next to my computer to let it upload. Then I come back later and turn it off.
However, and this happened today, if I come back and notice the watch is powered down I know that the activity did not get uploaded. The activity still shows in the watch, but won't upload. I went into Garmin Express and did a sync, which it says was successful, but it's not there.
How can I go about manually uploading this one activity so that it will show up in Connect and on Strava?
UPDATE: Currently doing a "Transfer All" function. We'll see how that works - taking a long time.
UPDATE2: The Transfer All did the trick. Didn't even know it was hiding there in the Activities menu. Even one from December just got added. Now time to go through and do my annual erasing of the activities.
