Teacher and writer Teddy Svoronos reports that iPadOS 27 changes what an AirPlay-connected external display shows when an iPad user taps outside the presenting app. He says this can expose private notes or poll results and disrupt GoodNotes, Keynote and PowerPoint presentations; Apple has not publicly confirmed a fix in the supplied material.
Teacher and writer Teddy Svoronos reported October 19 that iPadOS 27 changes an AirPlay presentation when users tap an app other than the one presenting: the external display can show the iPad’s full screen instead. He says this may expose private teaching notes or unrevealed poll results to an audience, while interrupting presentations in several apps.
Svoronos describes using an iPad to write on handouts that are projected through AirPlay, while also using the device to control a PowerPoint presentation on his Mac, check notes and view poll results before sharing them. In his account, the problem occurs when multiple windows are open and he taps outside the app that is presenting. He says the external display then switches to the full iPad screen, whether or not Stage Manager is enabled.
The effects vary by app, according to Svoronos. In GoodNotes, he says, the presenter view returns after he taps back into the app. In Keynote, the presentation exits; in PowerPoint, he says the presentation can become unusable until it is restarted. His concern is not only the interruption: other open windows may show information intended to remain private, and changing screens can distract an audience.
Svoronos says he filed a report with Apple using feedback code FB23615646. He also says the behavior had not changed in the latest iPadOS 27 betas he had tested. The supplied report does not include an Apple response, an independent technical analysis, or a statement that every iPad and presentation app is affected.
AirPlay Can Expose Presenter Windows
The reported behavior matters to people who rely on an iPad to present while keeping other work on the device private. Teachers may have class notes, student-related reminders or poll results open; conference speakers may be switching between slides, documents and reference material. If the external screen mirrors those windows unexpectedly, the consequences can include unintended disclosure as well as a visible break in the presentation.
The problem also concerns how presenters can use the iPad while an audience is watching. Svoronos says the ability to do other tasks without changing what the audience sees is part of his teaching workflow. If the report reflects a wider issue, users may need to avoid switching apps during a live presentation or use another device until they have tested their own setup. The source does not establish how widespread the behavior is, so the risk should be understood as a reported issue rather than a confirmed problem affecting all users.

A Change From iPadOS 26
Svoronos contrasts the reported iPadOS 27 behavior with iPadOS 26. He says the earlier system could make it difficult to tell which app controlled the external display: users had to swipe toward the Home Screen and select an app from the Dock to hand over the display when that app supported a presentation mode. He characterizes that process as confusing, but says the newer behavior—letting the most recently tapped app take over—is worse for his use.
His article is a first-person report grounded in his own teaching workflow and observations across GoodNotes, Keynote and PowerPoint. He says he had also raised the issue on a Mac Power Users episode in early September. The material provided does not include Apple’s explanation for the behavior or establish whether it is a deliberate design change, a software defect, or a problem limited to particular configurations.

Scope and Apple Response Remain Unknown
The available source is Svoronos’s account; it does not establish how many users or iPad models are affected, or whether the behavior can be reproduced across all apps, display connections and settings. It also does not provide a response from Apple confirming the issue, explaining the change or saying a fix is planned. Svoronos says the behavior persisted in the latest betas he had tested, but the report does not identify the exact beta build or testing conditions.
It is also unclear whether any reliable workaround prevents other windows from appearing on the external display while preserving a live presentation. Svoronos asks readers if they have found one, but the source material does not document a tested solution. Users should test their specific iPad, apps and connection before relying on them in a live setting.

Apple Feedback and Further Testing
Svoronos says he will update his report if the behavior changes and encourages affected users to send feedback to Apple, referring to his report code FB23615646. The next meaningful developments would be an Apple response, a software update that changes external-display behavior, or further testing that clarifies which devices and apps are affected.
Until then, presenters who depend on private on-device windows can check the setup before class or a conference, including what appears on the external screen when they switch apps. That precaution does not resolve the reported behavior, but it can reveal whether a particular workflow is vulnerable before an audience sees it. No fix or release timeline is confirmed in the supplied material.

Key Questions
What does Svoronos say happens in iPadOS 27?
He reports that, with multiple windows open during AirPlay, tapping an app other than the presenting app can make the external display show the full iPad screen.
Which presentation apps does the report mention?
Svoronos describes different effects in GoodNotes, Keynote and PowerPoint: the presenter view returns in GoodNotes when he switches back, Keynote exits the presentation, and PowerPoint may require a restart.
Has Apple confirmed a fix?
The supplied report includes no Apple confirmation or fix announcement. Svoronos says he filed a feedback report and that the behavior remained in the latest iPadOS 27 betas he had tested.
Does this affect every iPad user?
That is not established. The report describes Svoronos’s experience, but gives no information confirming the number of affected users, models or configurations.
Is there a known workaround?
The source does not identify a verified workaround. Presenters can test their own AirPlay setup before an event, but that is a precaution, not a confirmed fix.
