Oculus Quest heigth incorrectly initializing

I found the issue has to do with my position the last time I reset the view / recentered the menu. If I was standing up then the Guardian was correct when I launched my app, but if I was sitting down then the Guardian was elevated by distance between my sitting height and my standing height; the same amount the main screen moves up and down.

Is there a way to detect and correct this when the app launches?

I had this issue when using Eye Level.

Eye Level works well for a game that uses a table in the scene, since the viewer's eyes need to remain "above the table" whether they are standing or sitting when they arrive. AFAIK

However, if I would rather have the physical floor aka guardian floor remain matched to the scene floor, I used Floor Level with a code change. I have an older Oculus integration using a Character Controller of Height 1.5.

Without a code change, using Floor Level, the scene floor appeared 1 meter beneath the guardian floor when my OVRManager's GameObject's y value was 1.6 in the Inspector, but dropped to 1.02 with continuous slight variation while in play mode, the TrackingSpace's y value was 0, and standing or sitting affected the CenterEyeAnchor's y value between 1.1-1.7. The 1.02 is affected by my floorGameObjectCube being 0.02 yScale and at -.02 yPosition.

The fix is to get the TrackingSpace adjusted to offset the OVRManager's height. Set your OVRManager's GameObject inspector's y value to the play mode's calculated slight variation height, in my case 1.02 and add this script to you OVRManager's GameObject:

 void Start()
     {
         // When OVRManager is set to Floor Level, use this so the guardian base is lowered to sit at the scene's floor
         // rather than being ~1 meter too high
         GameObject tracker = GameObject.Find("TrackingSpace");
         Vector3 guardianOrigin = tracker.transform.position;
         guardianOrigin.y -= gameObject.transform.position.y; // Reads from the awake init value before Oculus liveCalculates it (not dependent on actual head motion)
         tracker.transform.position = guardianOrigin;
 }
