Thanks for the update @chad.timmerman; glad to hear you’ve got things working and a great suggestion for folks to double-check too 
Folks, I wanted to bring you some update on the progress of this. We’re still trying to pinpoint what may be the exact cause, however, something that Apple shared relatively recently was that the situation may well be improved with iOS 18: Bug: AASA file not fetched on app … | Apple Developer Forums. As iOS 18 is now GA, it would be great if anyone has any experience either way that they can share. Thank you
