I have connected my Garmin Connect account with Strava and if I view my Garmin Connect Account information it now shows that Strava has read permissions. However, my Garmin activity (I have only completed 1 activity so far using my new Garmin Edge 520), isn't showing up on my Strava dashboard? Is there something else I need to do?
24 hours and 1 further activity later and activities are now appearing on Strava Dashboard - fantastic!
