Apple recently updated its tablet operating system, but the new version is causing some headaches for teachers and professionals. If you rely on your iPad for presenting slide decks to a crowd, iPadOS 27 now risks exposing your private notes when you switch between applications on the device.
The software exposes your private windows to the audience
When users present over AirPlay, the new iPadOS behavior forces the external display to mirror whatever is happening on the primary screen. If a presenter taps into a different application to check notes or poll results, the audience sees that private window pop up on the projector. This replaces the actual presentation slide with the presenter’s personal workspace.
This visual disruption happens anytime you have multiple windows open. It triggers whether Stage Manager is active or not. In the past, iPadOS 26 handled this much better by allowing users to lock the presentation to the external screen while continuing to multitask privately on the tablet itself. Now, the system simply hands control to the most recently tapped application.

Different presentation tools handle the disruption poorly
Getting the presentation back on screen is an inconsistent mess that varies depending on the specific application you use. If you are presenting from Goodnotes, the software manages to restore the presenter view once you tap back into its window. Other tools are far less forgiving.
Keynote will exit the presentation entirely when you click away, forcing you to start over. PowerPoint acts similarly, requiring users to manually restart their slideshow before they can continue. The consistency of this behavior suggests it might not be a simple bug that app developers can patch on their own. Instead, it appears to be a systemic change from Apple.
As Apple rolls out the iPadOS 27.2 release candidate for testing, users are hoping the company takes notice of this regression. Until a reliable fix arrives, presenters might want to stick to a Mac if they need to multitask during a live speech.
