Question details
The user is experiencing delayed synchronization between the OneNote iPad app and the desktop application, which requires a manual refresh to resolve.

- Product
- Microsoft OneNote
- Device & OS
- iPadOS
- Scenario
- Syncing note updates between the iPad application and the desktop version of OneNote.
- Observed behavior
- Synchronization is significantly delayed. Standard troubleshooting steps, such as reinstalling the app or signing out of the account, do not automatically resolve the issue.
Ensure your iPad is connected to a stable Wi-Fi or cellular network, and check that you have sufficient OneDrive storage space, as full storage can halt all synchronization processes.
Force Manual Sync and Adjust iPad App Settings
Bypass the automatic sync delay by manually refreshing the notebook list and configuring iPad system settings to allow background data usage for OneNote.
Since reinstalling or signing out often fails to fix this specific sync delay, adjusting the background data permissions and utilizing a manual refresh is the most effective workaround until Microsoft releases an official patch.
Open the OneNote application on your iPad, navigate to your notebook list, and swipe down on the screen to force the app to fetch the latest data immediately.
Open your iPad's main 'Settings' app, scroll down the left panel to find and select 'OneNote', and toggle the switch next to 'Background App Refresh' to the ON position.
In the same OneNote settings menu, ensure that 'Mobile Data' is enabled so the app can continue to sync even when you are disconnected from a Wi-Fi network.

Try WPS Office for Seamless Document Management Across Devices
If you are tired of synchronization issues and slow updates with Microsoft apps, consider switching to WPS Office. It provides a lightweight, unified workspace for your documents with fast, reliable cloud syncing across all your devices.

Frequently Asked Questions
Why does OneNote take so long to sync on my iPad?
Synchronization delays can be caused by large notebook sizes, poor network connectivity, or having the 'Background App Refresh' setting disabled. In some cases, it is a software bug within the app itself that requires an official update.
Will reinstalling the app fix the OneNote sync delay?
As reported by many users, reinstalling the app or signing out of your account often does not resolve this specific synchronization delay. Manually forcing the sync via a pull-down gesture is a more reliable immediate workaround.
How do I know if OneNote is currently syncing on my device?
You can verify the synchronization status by looking for the sync icon (a circular arrow) next to the name of your notebook. If there is an issue, a small warning triangle will appear in its place.
