Hello, thanks for sharing the screenshot and reporting the issue.
As far as we tested, xFanatical Safe Doc is able to block the AI Overview from our end. Please see the demo below. But you're right. Google updates search engine from time to time, and it may happen when Google recently rolls out a new version gradually.
Please first try if xFanatical Safe Doc receives the correct policy value from the student's device.
- In the student's browser, go to chrome://policy.
- Scroll down to the xFanatical Safe Doc section.
- Find the policy BlockGoogleSearchAIOverview. Is the policy value true?

If the policy value is
true but it is still not blocking the AI overview, please contact us at
sup...@xfanatical.com. We'll reproduce, investigate the issue and provide a fix.
Thank you.
