I joined the Tandem Strava Club with my usual account, as I didn't know there was a problem with that. It seems I joined, as it shows in my Activity, but our ride didn't show up in the Club Activity. After reading the notes, it appears that I should use a different email and membership. Now I can't find a way to unjoin. But if I can unjoin, I can rejoin with a separate account, but then I don't know how to tell Strava on my android phone which account to use. I use a Cateye uploading to Strava on my half-bike, and not sure how that would handle it. In my current Strava, I just switch the "gear" to the Tandem when saving it. Seems simple to have Strava direct it to the Tandem club that way.... Any hints on resolving the unjoin issue would be appreciated. We are enjoying the tandem!
