This is issue is for iOS only. In my app I show the user planes that generate, or some other use of planes - I'm happy to spawn the planes. When the user is happy with the plane, they spawn an object on the plane. From here I don't need the Plane Manager anymore, so I use enabled = false to turn it off. Turning it off causes the entire scene to drift for a few seconds, then it snaps back to the original position. Any clues to stop this drifting from happening? Anyone else having this issue? On Android this doesn't happen.
