I hadn't seen anyone confirm this yet when I looked so I figured I'd post here in case anyone else is wondering.

The steam controller is fully functional when paired via bluetooth to my apple tv. All buttons and features are present when connected via the steam link app including touchpads and gyro.

it retains only normal button functions for navigating elsewhere in the apple tv, just like the xbox of dualsense controllers.

I have found the BT connection to be superior to the puck in my living room (sitting 10ish feet away from the puck connected via a 100' usb cable back to my pc).
