iOS AR app shows black background rather than a camera overlay in production

I believe your demo video was distributed, I see the yellow dot in the bottom left corner of the app.
The Settings I changed in addition to the certificate also have the “Force 32bit Floating Point Precision” option, which defaults to false, which I turned on, because if I didn’t my package would disappear on testFlight
Maybe there are some details we haven’t noticed, like plugins?
