Check if motion controllers are tracked not working on Windows MR?

If IsTrackingAvailable(), you will have at least 3-dof tracking, if HasValidTrackingPosition() you will have 6-dof

So:
if (IsTrackingAvailable() && !HasValidTrackingPosition()) // 3-dof
if (!IsTrackingAvailable()) // All tracking data is unavailable

I’ll need to take another look at the controllers - IsTracked will be true for 6-dof, we may need to add a new BP function for controller 3-dof

This seems to have changed again in 4.24, but it seems like an ok change.

I now to this every frame instead:
