Only the AR Camera Background rendering in URP

Stymied after a couple hours of trying different combinations of things here… In my iOS URP app, when I activate the AR Camera Background, everything else disappears. Even more odd, the shadow or AO is being drawn over the AR Camera Background–I can see the faint edges of my geometry. (See below.) Anyone have thoughts?

I’ve ruled out:
-Camera ostprocessing on/off
-Postprocessing enabled/disabled in the URP asset
-Camera stacking used/not used
-Depth texture on/off
-Opaque texture on/off
-Light estimation on/off

Here’s a small sphere stuck to a chair plane:

Is HDR off?
Is ‘disable depth and stencil’ unchecked in the Player settings?

What are your mobile device, iOS version, Unity version, and URP version?

This is not a problem in our sample app. I recommend that you take a look there for inspiration? GitHub - Unity-Technologies/arfoundation-samples at 5.1 · GitHub
