VPP tokens are good for one year. Approximately 30-days before expiration, a notification will appear to all schools when a token is about to expire. If your school is one of the listed, the token must be renewed before its expiration date or any deployed apps will be revoked on devices.
Jamf notifications (top-right “lightning bolt” icon when logged in) are system-wide, meaning that all users can see all notifications. Because of this, you will see notifications that may belong to other schools other than your own. You only need to be concerned with notifications that relate to your school.
