I was on vacation and had three activities on my 920XT before I was able to upload to Garmin Connect. The most recent activity synced with Strava but the first two did not. I've never had this issue before because I always upload my activities as soon as I do them and have never had more than one to upload. I successfully uploaded all three to Garmin Connect but only the latest one got synced with Strava. Is there a way to manually sync individual activities with Strava so I can fix this?
