Myself and my partner zwift together regularly. She uses a smart trainer connected via Ant+ and i use a dumb trainer with my PowerTap Hub PM via BT and the companion app.
Recently my machine takes over her smart trainer and start feeding my watts to her trainer subsequently reducing or increasing resistance depending on the situation. Im not connecting to her trainer before we start in the pairing screen, it just does it every now and then but it does happen everytime we ride together.
Can anyone offer any advice on how to stop my machine taking over?
