iPadOS 15 PWA start QuickLook only in model mode and AR not working

[PetrSemrad]

After updating to iPadOS 15 (then to 15.0.1) and installing the application in safari as PWA, after opening QuickLook it´s not possible to display the object in AR.
Only safari without installing a PWA application and opening a QuickLook object in AR works without problems

Curious, was this working on a previous version of iOS? Are you getting any error feedback that you can provide?

Yes, everything worked fine on the previous version of iPadOS 14.x.
It's interesting when I try as ios-src for example https://xxx.com/xxx.usdz#applePayButtonType=buy&checkoutTitle=Biplane%20Toy&checkoutSubtitle=Rustic%20finish%20with%20rotating%20propeller&price=$15
So in a safari without installing PWA, everything works, but not in the installed application. As if the safari didn't pass attributes after #

It looks like a bug in iPadOS
