I tried updating the MagicLeap internal version of the MRTK samples project to use the feature/XRI3 branch (@ 2e7da36). It seems to be mostly working after performing the upgrade (some automatic and a few minor manual script changes were needed -- there were also complaints about XROrigin not being a parent for ARMeshManagert iirc).

Two problems I saw so far:

1. I couldn’t scroll the volumetric UI panel in the hand interactions demo — it worked in editor. The ScrollRects in ScrollingExample and VirtualizedScrollRectList seem ok
2. The ray visual for the ML2 controller didn’t always show up -- this is likely internal to the ML2 support package and we'd need to debug
