Hi SColley
Thank you for reaching out to the Microsoft Q&A forum.
I understand your concern about not being able to close the notebook after updating OneNote for iPad, especially since using the "Delete All Notebooks" option under Reset OneNote may risk losing any changes that have not yet synced.
I researched this issue but could not find any official documentation or information confirming this specific behavior in OneNote for iPad version 16.112.2.
Please note that we are not Microsoft Support. This is a user-to-user community forum, and moderators here do not have access to your environment or Microsoft's backend systems, and we are unable to escalate cases directly to Microsoft’s internal teams. We can only provide guidance based on publicly available documentation and community experience.
In this case, I recommend contacting Microsoft Support by raising a support ticket so they can investigate this further and collect the necessary information from your environment.
For further instructions, you can follow this guide: Get support - Microsoft 365 admin | Microsoft Learn.
Thank you again for your understanding, and I hope the issue can be resolved soon.
