Why are my wife's activities showing up on my Mobil Link

We are running Zwift on an Apple TV 4k

My wife’s activities are showing up on my Mobil Link “Activities” page and our KOM PR’s are showing up on each other’s rides.  We each have our own individual accounts but use the same Apple TV and app. 

Hi David

Is this normal if you ‘follow’ each other?

Ride On!
