I've linked my Quest to my PC with a link cable and when I run OVRManager.boundary.GetConfigured() it always returns false in play mode in the Unity editor.
My guardian system is set up properly, so I'm not sure if this is because of the conversion to the Rift is throwing it off or what.
Not being able to take advantage of hand tracking via the link cable I get, but the guardian system too? It would be great to have a solve for this so I can use the boundary system while I'm setting up my world via link cable.
