OneNote keeps crashing when hitting UNDO

Everytime I use OneNote on my Ipad it keeps crashing whenever I want to use the Undo button. I habe already updated the ipad as well as OneNote, restarted the ipad, reinstalled the app and disabled the stage manager but it all didn‘t help. I believe the problem lies in OneNote itself or its compatibility with IOS. I‘d really like some help on this topic as it gets very much annoying and really stops the entire workflow

    This matches a known pattern on iPad where OneNote can fail even after the app and iPadOS are fully updated and after reinstalling. In that case, the practical next step is to report it directly from OneNote so the product team can investigate the crash.

    Recommended steps:

    1. Open OneNote on the iPad.
    2. Go to Settings.
    3. Tap Send Feedback and report that OneNote crashes specifically when tapping Undo.

    Since the issue happens only on iPad and persists after these steps already tried:

    • updating iPadOS and OneNote
    • restarting the iPad
    • reinstalling OneNote
    • disabling Stage Manager

    that points more to an app bug or iPadOS compatibility issue than to a basic local setup problem.

    A few supported checks are still worth doing:

    1. Make sure all Microsoft Office apps on the iPad are updated, not just OneNote. OneNote on iOS shares Office identity components with apps like Word, Excel, and PowerPoint, and outdated Office apps can affect OneNote behavior.
    2. Sign out of OneNote and sign back in.
    3. If sign-in or sync behavior also seems abnormal, clear stored OneNote sign-in credentials:
      • Go to iOS Settings > OneNote > Reset OneNote > Delete Sign-In Credentials and turn it on.
      • Fully close OneNote.
      • Reopen OneNote and sign in again.
    4. Force a notebook sync by pulling down the Notebooks list until the spinning progress indicator appears.
    5. If notebooks are very large, reduce notebook size where possible by lowering the number of sections, pages, or heavy page content. Large notebooks can reduce responsiveness on iPad and iPhone.

    If the crash is only tied to Undo and not to sign-in or sync, the strongest supported path is still Send Feedback from within the app, because the context shows similar persistent iPad-only failures being treated as known app issues rather than user-fixable configuration problems.
