Simultaneous MxInk and Hands does not with META SDK v72 SimultaneousHandsAndControllers samle scene

Goal: I’m working with a Quest 3 headset and controllers to develop a VR app that tracks: virtual hand (meta sdk hand tracking) on one side and the MXInk on the other side. 

Problem: When I open the "SimultaneousHandsAndControllers.unity" sample scene in Unity 2021.3.45f, the sample works fine, I see one one side the controller and the virtual hand on the other side. However, as soon as I power on the MXInk controller, the virtual hands disappear, and only the MXInk controller is tracked.

I’ve spent the last two weeks experimenting with different controller settings, but I haven’t been able to get it to work. Has anyone experienced this issue or found a solution? Any guidance would be greatly appreciated! Thanks!
