Marker-Based LBSS features PCVR APIs unavailable because it uses OpenVR Loader instead of OpenXR

Did anybody have any success getting the MBSA working? I've run into the same issues. Scanning the markers on map creation reports success but they appear to have zero impact on the alignment.
It's still unclear whether we need to inject the markers into our app using the PLAYER00InitMA command. It's included as a step in the documentation but we're told above that it isn't necessary. 

1) Do I need to call WVR_GetParameters with PLAYER00InitMA in my app in order for MBSA to work?

2) If so, what is the correct format? Should I include the pose in the input parameter, or just the id, behaviour and size?

3) Is a particular WaveSDK version required for this? I'm using 4.5.

4) I'm using Unreal Engine. Are there any other steps required to enable marker tracking, similar to hand or eye tracking? 

5) Is there any way to debug what's happening? Can I view the map data in some way to confirm that it has taken into account the ArUco markers?

Thanks in advance!
