Unfortunately this issue is NOT fixed in iPadOS 18.0.1.

There are definitely bugs in this area in iOS 15+ (and iOS 16+). What I am seeing is the delegate call is made with 1 entry on the initial call, and then 0 entries on all subsequent calls. This all worked perfectly in iOS 14 and earlier. I have tried numerous work-arounds without success. For example, I've tried saving the selected paper on the first call - and then returning the same paper on subsequent calls. This doesn't work because the orientation is incorrectly applied if you do this. Can you let me know if you figured out any work arounds OR you raised this formally as a bug with Apple?
