Using Zwift through Apple TV

Can anyone help?

I have a Wahoo Kickr and use Zwift for indoor cycling. I have zwift on my iPhone and the Zwift app all runs fine on that. However, I have Apple TV set up onto my tv in the attic with the zwift app on this. It has all connected totally fine before but for some reason I can no longer get zwift to run on the tv?

When I try too connect the power source I get nothing. Im assuming the bluetooth connection has dropped off? But I can not for the life of. me get it back up and running!

Any help greatly received.

Thanks

Richie
