OneNote - changes are not being instantly synced upon changes

As title.

Settings has OneNote set to sync when there are changes but it isn't doing, so data often isn't synced at all.

I am using the free OneNote app for windows and am on windows 11

It will sync eventually, but after 15 mins if not more. But it should be syncing straight away upon changes and it isn't. It used to. I have used this app a long, long time.

It is not an issue my end nor my device as I tested on a 2nd machine and the same there, so this is the app itself doing this.
I worked in IT for over a decade so I have done my testing on 2 machines to prove it is not my machine.

It used to work ok as I have used OneNote for over 15 years.

Windows 11 and the free OneNote app from the Microsoft app store on windows.

    As I said its nothing my end, everything is fine.
    Also I had added a photo to show my setting is already set to “Sync automatically whenever there are changes”, but your (what looks like) AI reply asked me to check it was ticked.

    It definitely used to be almost instant after making a change that it would sync. Now its like15 mins.

    Used OneNote for so many years and never had this before. That is why I asked as this was not happening before. It was faster previously.

    So if that is normal, then its definitely changed.

    I am finding things aren't syncing because I didn't leave onenote open on my PC for 15 mins, so I am having to manually sync to make sure the changes are made.

    OneNote sync is not truly “instant”; even with “Sync automatically whenever there are changes” enabled, the client batches changes and syncs them on a schedule and when certain triggers occur (section switch, app idle, explicit sync, etc.). If changes are eventually syncing (after ~15 minutes) and there are no sync errors, this behavior is within the normal pattern described for OneNote and not a client-side failure.

    To reduce the delay and confirm sync health:

    1. Verify automatic sync is enabled
      • In the OneNote desktop app, select File > View Sync Status.
      • In Shared Notebook Synchronization, ensure Sync automatically whenever there are changes is selected.
      • Click Sync All once to force a full sync and clear any backlog.
    2. Check for sync errors per notebook/section
      • Go to File > Info > View Sync Status again.
      • Look for any notebook with a yellow warning triangle and use Sync Now next to that notebook to see if an error is reported.
      • If only a specific section or page is slow or stuck, follow the “sections or pages won’t sync” workaround: create a new section, copy pages into it, then press Shift+F9 to manually sync and see if that section syncs promptly.
    3. Confirm service and connectivity
      • Ensure the device has stable Internet connectivity; OneNote relies on this for timely sync.
      • If the notebook is on OneDrive or SharePoint, open it in a browser via https://www.onenote.com and verify that recent edits appear there. If the web copy is current, the delay is likely between clients rather than a server issue.
    4. Avoid configurations that interfere with sync
      • Do not place notebooks on Windows Offline Files shares; this can cause delayed or conflicting sync behavior because OneNote’s own cache conflicts with the Windows Offline Files cache.
    5. Use manual sync when immediate propagation is required
      • When edits must appear on another device right away, use File > Info > View Sync Status > Sync All (or Sync Now for a specific notebook) before switching devices.

    If there are no reported sync errors and notebooks are up to date after a manual sync, the observed delay is consistent with OneNote’s normal sync model rather than a misconfiguration on the devices.
