iOS Quick Look Shows Blank AR Experience for .glb Files

[BryanMThomas]

We are using to render .glb files on both Android and iOS.

On iOS, when users tap the "AR" button and enter Quick Look, the experience is blank, no model shows up in either AR or VR modes.
On Android, the same .glb loads correctly in both AR and VR (mode-only view).
On iOS, Quick Look launches, but the 3D object is not visible.
We suspect this may be due to the .usdz conversion?

<model-viewer
    ref={modelViewerRef as React.RefObject<HTMLElement>}
    src={file.glb}
    alt={"alt Text"}
    poster={poster}
    ar={false}
    ar-modes="webxr scene-viewer quick-look"
    disable-tap
    auto-rotate={false}
    disable-zoom={false}
    auto-rotate-delay={30000000}
    camera-controls
    camera-orbit="180deg 75deg 95%"
    style={{
        width: "100%",
        height: "100%",
        display: "block",
        ...style,
    }}
    loading="eager"
    reveal="auto"
/>

Questions
Is there a known issue with .usdz conversion or and Quick Look on iOS?

Any tips for debugging Quick Look on iOS when models appear blank?
