My experience is that when an app without a scene delegate is built with Xcode 26, it will run on an iOS 27 device. If built with Xcode 27, it will crash on launch.

I just got this error message when trying to download my weekly sales report. My daily reports for Monday 06-05 thru Sunday 06-11 all show positive sales for multiple products. But the weekly report for Jul-05 thru Jul-11-2023 returns the above error message via Reporter.jar, and "No report is available because there were no sales for the selected date." via the App Store Connect web page.
