I ran two times earlier tonight. Both activities were uploaded to Garmin Connect successfully via iPhone. However, only the second activity was uploaded to Strava - the first activity is nowhere to be found on Strava. So I went to my Garmin Connect account and exported both the TCX and GPX file for the first activity so I can upload it manually to Strava only to get an error, as shown in the picture attached.
Any ideas?! ciq.forums.garmin.com/.../1251723.png
