Apple broke an essential presentation feature of iPads

# Summary As of iPadOS 27, Apple broke a critical presentation feature by changing how external display priority works during AirPlay. When multiple windows are open, tapping anything other than the presenting app now causes the external display to show the entire iPad screen, exposing private notes and poll results to audiences and disrupting presentations in apps like PowerPoint, Keynote, and GoodNotes. The author proposes that presenter mode apps should maintain external display priority until the presentation is explicitly stopped, and urges users to file feedback with Apple about this regression.
