How to Fix OneNote Sync Issues Between Windows PC and Android
Question details
The user needs to resolve synchronization issues between the OneNote application on a Windows PC and an Android device by identifying which device is failing to sync.

- Product
- Microsoft OneNote
- Device & OS
- Windows and Android
- Scenario
- Trying to access updated notes across multiple devices but finding that changes made on the Windows PC do not appear on the Android app, or vice versa.
- Observed behavior
- OneNote content entered on one device fails to synchronize with the other, creating inconsistent notebooks and missing data across platforms.
Ensure both your Windows PC and Android device have a stable internet connection, are not in airplane mode, and are signed in to the exact same Microsoft account.
Isolate the Sync Issue Using OneNote on the Web
Use the web version of OneNote as a baseline to determine whether the Windows PC or the Android device is failing to upload or download changes.
Because OneNote syncs through Microsoft's cloud servers (OneDrive), the web version always displays the data that has successfully reached the server. Comparing your local apps to the web version quickly pinpoints which device is causing the bottleneck.
Open a web browser on your PC or mobile device and navigate to https://www.office.com.
Sign in using the exact same Microsoft account associated with your OneNote notebooks.
Open the OneNote web application and locate the specific notebook that is failing to sync.
Compare the text and pages in the web version with the content shown on your Windows PC app and your Android app.
The device whose content differs from the web version is the one experiencing the synchronization failure.

Manually Force a Sync on Both Devices
If you have identified the device that is not syncing or if the sync is simply stuck, manually forcing a sync can push or pull the latest changes.

- 1. Download the App: Visit the official WPS Office website to download the Windows desktop version, and search for WPS Office in the Google Play Store for your Android device.
- 2. Sign In: Create or sign in to a WPS account on both devices.
- 3. Enable Cloud Sync: Save your documents to WPS Cloud to automatically access your updated files anywhere.

Frequently Asked Questions
Why does OneNote sync take so long between devices?
Sync delays can be caused by a poor internet connection, exceptionally large notebook files (such as those containing heavy PDF printouts or large images), or temporary server-side issues with Microsoft OneDrive.
How do I know if my OneNote is syncing properly?
Look for the sync status icon next to the notebook name in the app. A green checkmark indicates a successful sync, while a red 'X', a warning triangle, or a continuous loading circle indicates a sync error.
What should I do if forcing a sync doesn't work?
Try closing the notebook and reopening it, signing out and back into your Microsoft account, or clearing the cache of the OneNote app on your Android device. Always ensure any un-synced offline edits are manually backed up (e.g., copied to another app) before clearing data.
