ArcHandles and Handles do not work correctly on Meta Quest 3 VR. The small squares that accompany the adornment floats to odd positions as you move your head. And the light beam from the right-hand controller does not connect with the adornment (not without a great deal of luck). I found that if I hold my headset level, looking at the horizon straight ahead, and move the light beam slowly, I can sometimes get it to highlight the arrow and grab it. But the beam is not pointing at any logical place.

Close the splash screen and select the SpawnLocation, then select any of the Move/Scale/Rotate tools (gui buttons) at the top of the screen. Colored arrows/circles will appear on the SpawnLocation. Other devices (mobile, Windows, Xbox) have no trouble grabbing and dragging the colored arrows/circles.
While in an experience, the ArcHandle instance adorns a part with colorful circles and balls that you can drag to rotate a part, similar to the Rotate tool in Studio. The Handle instance shows arrows that can be dragged to let the player position a part or model. These handles work fine on these devices (mobile, Windows, Xbox – virtual cursor). But they do not work correctly on the Meta Quest 3 VR Headset.
