Dear @MAN Charissa [Willetton Senior High School],
Hello,
Thank you for updating!
For your situation, please take note this point:
- OneNote Online; especially Class Notebook features; relies heavily on modern web technologies.
If Chrome is outdated, or if certain extensions or browser settings interfere, it can cause errors like the one you've encountered.
Besides that, since the page distribution feature still works when using Microsoft Edge, it strongly suggests that the problem is related to the web browser, specifically Google Chrome.
Note: Microsoft Edge is a product developed by Microsoft and is fully optimized for Microsoft 365 services like OneNote, Teams, and Word. For the best performance and reliability, I recommend using Microsoft Edge, especially for tasks like distributing pages in Class Notebooks.
Although Chrome is a third-party product and not developed by Microsoft, I’ve tried to research possible solutions you can infer:
1. Update Google:
To ensure you're using the latest version of Chrome, you can infer this article to check for updates and relaunch if needed.
For reference: Update Google Chrome - Computer - Google Chrome Help
2. Clear Cache and Cookies:
When you visit websites, Chrome stores temporary data like images, scripts, and login info to help pages load faster. However, over time, this data can become outdated or corrupted, causing the issue.
So, clearing cache and cookies helps reset the browser’s memory for those sites, allowing them to load fresh and correctly.
You can follow detail steps by steps in this article: Clear cache & cookies - Computer - Google Account Help
Additionally, you also disable extensions since it helps you identify if one of them is causing the issue. If OneNote works fine after disabling them, you can re-enable extensions one by one to find the culprit.
