Simply put, for some reason when I opened onenote today the side tabs were massive. I've included screenshots for reference. Why did this happen and how do I fix it? I skimmed through the settings, and nothing jumped out at me.

    Hi Brock,

    This issue is often related to one of the following:

    Display Scaling or Zoom Settings

    Accessibility Settings

    Temporary UI Glitch App Update or Theme Change

    what you can try is : Restart OneNote and your device: This can clear temporary UI glitches.

    Check Zoom settings: In OneNote, go to View > Zoom and reset it to 100%.

    Inspect Display Settings: On your Mac, go to System Settings > Displays and check if scaling is set to “Default” or “More Space.”

    Review Accessibility Settings: Check System Settings > Accessibility > Display for any text size or UI scaling options.

    Try resizing the window: Sometimes dragging the window to a different size resets the layout.

    Let me know how it goes, Happy to help!
