Hi,
I ran into the same issue earlier, but just to confirm, starting with iOS 26 beta 9 this behavior seems to be fixed.
After uninstalling and reinstalling the app, the ATT prompt is shown again as expected, and the IDFA is properly reset.
So it looks like it was a temporary bug in earlier betas rather than an intentional change.
Can close this thread.
