@alanbernier, Did you edit your Strava activity? I have read that making an edit, creates another entry in the queue. You can check status here: https://citystrides.com/status
At the bottom of the “Strava Sync” section, you can click to show Strava activity numbers in the queue. You can also click the Strava activity number, to see that activity on Strava (opens a new page).
If you see the same activity number more than once, it was likely due to an edit.
I see this when I edit my activity to add the shoes I wore.
No need to re-sync here, CityStrides will catch up, eventually. Only if your queue is empty, and you still don’t see your activity, do you need to do anything. See: Reply Here If You Have Missing Activities
