OneNote goes blank on IPAD iPadOS 26.4.1 (23E254) when switching between applications

Yeah… 16.108 just fails to restore its render surface after an app‑switch on 26.4.1, so closing n’ reopening is the only stable recover you can do right now. If it still whites out, a clean reinstall + an iPadOS reboot is basically the last reliable step until Microsoft ships a fixed build.

Dear @Ron.M,

Thank you for your additional information. Based on your description, since the notebook opens normally when accessed from a Windows computer and also from your iPhone running OneNote version 16.107.4 on iOS 26.4.1, this confirms that the notebook itself is not corrupted and is syncing correctly from the OneDrive/SharePoint side.

I'm currently aware of a recent compatibility issue affecting OneNote on Apple devices running the latest iPadOS versions (26.4.1). In some cases, the OneNote app may fail to correctly resume its session when switching between applications, which can result in notebooks appearing blank or not loading properly.

Please understand that as a forum moderator, my role is limited to providing general guidance and troubleshooting support. I do not have access to your organization’s backend systems or sufficient internal tools to perform advanced diagnostics.

Therefore, to ensure the issue is properly tracked and escalated, I recommend contacting your IT administrator and asking them to report the issue through the Microsoft 365 Admin Center. Submitting the report this way allows Microsoft Support to investigate it in the correct tenant context and route it to the appropriate product team.

• Go to the Microsoft 365 admin center at https://admin.microsoft.com, and sign in with an admin account.
• In the left-hand navigation of the admin center, go to Health > Service health, or select the Service health card on the Home dashboard.
• Selecting Report an issue, and completing the short form
• For reference: How to check Microsoft 365 service health

For now, it may be necessary to wait for an official fix or further update from Microsoft. If I receive any updates, guidance, or confirmation of a resolution from Microsoft, I will reach out to you as soon as possible to share the latest information.

Additionally, if you are using business account, your organization’s IT administrator can help you create a support ticket with Microsoft Support in the Microsoft 365 Admin Center for further troubleshooting. They will have access to the appropriate administrative tools and backend resources that may be required to investigate this issue in more detail. For reference:  Get support | Microsoft Docs

In the meantime, I recommend you try accessing the notebook via a web browser by signing in to OneDrive and opening it in OneNote for the Web or using OneNote on your computer. This can help you continue working while improvements are being made.

Thank you for your patience and understanding. I'm looking forward for your reply.

Dear @Ron.M,

Based on your description, OneNote goes completely blank after switching between applications and only returns to normal after force‑closing. This might be due to a recent compatibility issue between the latest iPadOS/macOS update and the current OneNote app version.

OneNote app has not yet been fully optimized for the latest operating system update, and the app may not correctly resume its session when multitasking between apps. In these situations, the application UI may stop responding even though your notebook data remains safe in the background.

In this case, to help me narrow down the issue and provide you the best paths, could you please help us confirm a few details below?

• Does the white screen occur every time you switch away from OneNote, or only after using specific apps (e.g., Safari, Outlook, Teams)?
• Are you using OneNote in Split View when the issue happens?
• Does this happen with all notebooks, or only a specific notebook or section?
• After reopening OneNote, does your content reappear normally?
• Are you signed in with a personal Microsoft account (@outlook.com/@hotmail.com) or a work/school account (@company.com/@onmicrosoft.com)?
• Whether this issue started before or after you updated your iPadOS to version 26.4.1?
• Does the same notebook open normally when accessed through OneNote Online in a browser?

In the meantime, I recommend you the following in the meantime:

Step 1/ Uninstall and reinstall the OneNote app in the AppStore

Note: Make sure OneNote is updated to the latest available version and keep your device up to date with any newer OS patches

Step 2/ Restart the iPad

I hope the information shared helps point you in the right direction. Please try the steps above and let me know if they work. If not, we can continue working together to narrow this down.

The first response may not always resolve the issue right away, but with your help and more details, we can work toward a solution.

Thank you for your patience and understanding. I'm looking forward for your reply.
