A fellow Zwifter is uploading rides to my Strava

A fellow Zwifter is uploading rides to my Strava. They aren’t using my Zwift account from what I can see, but somehow they have linked to my Strava so their rides show in my feed. Any idea how I can get this link stopped? They are probably reporting similar issues as they can’t see their activities in their own feed.

cheers. 

You could try this: disconnect your Strava account from Zwift by clicking on “Revoke Access” at https://www.strava.com/settings/apps . Then reconnect your Zwift account to your Strava account. 

Thanks, just tried that so will see if any more mystery rides appear.
