Hello Zeeshan,
Thanks for asking your query.
Your Copilot agent is continuing to return answers based on documents from a SharePoint site despite having access blocked because of the Permissions Update Delay as SharePoint permissions changes can take 24-48 hours to fully index and be reflected. Also please check the configuration and make sure that the permissions and security controls are properly set to show the new restrictions. You can also refer below documentation links:

Thanks,
Keshav
