Understanding OneNote Sync
Before we dive into troubleshooting, let's understand how OneNote sync works. OneNote saves your notes in the cloud, allowing you to access them from any device. However, sync issues can occur due to various reasons, such as internet connectivity, app glitches, or even conflicts with other software.
