I can't seem to get the MARS Device View to be navigable. In Simulation View or Game View I can navigate with WASD and right-click (like normal Unity), although game view is (by default) restricted to "head level" movement on the Y-Axis (unless it is unlocked.) But the Device View stays locked in place, even if I've launched the simulation with the toolbar "Play button". It doesn't respond to navigation input at all. ?? FWIW, I'm only using simulated image markers in my simulation scene at this time.
