Scenario

Update Software and Restart the iPad

The most effective first step is to ensure your app and device OS are fully updated, which clears temporary glitches causing the sync to hang.

Software updates often contain essential bug fixes for synchronization loops and memory management issues on iPadOS.

Navigate to Settings > General > Software Update. If an update is available for your iPad, download and install it.

Restart Your Device

Press and hold the power button and either volume button until the power-off slider appears. Drag the slider, wait 30 seconds, then press the power button again to turn the iPad back on.

Frequently Asked Questions

Why does OneNote freeze on my iPad exactly when I connect to Wi-Fi?

When your iPad connects to the internet, OneNote immediately initiates a background sync. If it encounters a massive notebook (especially those over 2 GB) or highly complex formatting originally created on a PC, the iPad's memory is overwhelmed trying to process the data, causing an immediate freeze.

Will reinstalling the OneNote app fix the freezing issue?

Reinstalling the app can clear a corrupted local cache, which sometimes resolves sync hangs. However, if the root cause is a notebook that is simply too large, the issue will return as soon as it tries to redownload it. Be warned: deleting the app will erase any local notes on the iPad that haven't synced to the cloud yet.

How can I check the file size of my OneNote notebook?

You cannot check the file size directly within the iPad or mobile app. To check the size, log into your OneDrive account on a web browser, navigate to your 'Documents' folder (or wherever your notebooks are stored), and look at the file size listed in the details column.

Can I force a specific notebook to stop syncing on my iPad?

Yes. If the app freezes immediately, turn on Airplane Mode first. Then open OneNote, tap and hold the name of the problematic notebook in your list, and choose 'Close Notebook'. This removes it from your local device and prevents it from attempting to sync when you turn Wi-Fi back on.
