Physics in VR Browser has stopped working

Physics was working in VR about a 10 months ago. Some time between then and now, the VR Browser has changed and it is no longer working. We did nothing to our code. We have tested going back to ZIM 015 and it is like the physics world is not being stepped. As soon as we select the menu button - it pops up a menu with VR still in the background - and then the physics works. But when we close the menu, it no longer works. No forces are being applied.

We tried a timer to add a ball that will fall. It shows and does not fall until pressing to exit VR and then it falls.

So... I guess looking to see what might be interfering with the step ticker.

If anyone with a headset could test this out

Then view it in the Quest Browser and press ENTER VR at the bottom - a ball will appear after 5 seconds and it should fall. Then you should be able to throw around the ball.

But in VR it seems stuck until you go to quit VR and then it moves in the background. That is if you enter VR before 5 seconds of loading the app page.
