• Blogger
• Google Cloud Platform
• Location History

Here is the full list of restrictions and services that will no longer be available for users under 18.

Please update the age-based access settings in your Admin console to indicate all users above the age of 18 (i.e. teachers, staff) before September 1, 2021.
