How to unblock?

To unblock something on a school Chromebook, you typically need to contact your school's IT administrator. Schools often implement restrictions on devices to ensure a safe browsing environment for students, and these settings can only be changed by authorized personnel. If you believe a site or application is incorrectly blocked, providing specific details to the IT department can help them review and potentially unblock it.
