Meta XR Simulator Physical Controller Issues

Hi,

I have begun using the physical controller connection in the Meta XR simulator to test more complex controller gestures but have immediately run into issues.

The forwarding server is running on the headset, and the simulator successfully connects, but the controllers do not move, and just sit at the origin motionless.

If I restart the Unity editor, the physical controllers will work once, but the next time I enter play mode they will not work until the editor is again restarted. There are no error logs or other obvious reasons for this failure. I am on Unity 6000.0.55f1 using v77 of the Simulator and the Meta SDK.
