Revoke app assignments in Apple Configurator
You can revoke apps assigned by your Managed Apple ID or personal Apple ID account in Apple Configurator.
In Apple School Manager, this can be an account with the role of Instructor or Manager with privileges to buy apps and books, or the role of Content Manager, Site Manager, or Administrator. In Apple Business Manager and Apple Business Essentials, this can be an account with the role of Content Manager or Administrator.
Note: You must have a license for each device that the app is assigned to.
In Apple Configurator , choose Account > Sign In, and sign in with one of the following:
Your Apple School Manager, Apple Business Manager, or Apple Business Essentials Managed Apple ID that has privileges to buy apps and books
The personal Apple ID that was used to purchase the apps or books
Enter your six-digit verification code.
Choose Window > Volume Purchasing Assignments.
Click the disclosure triangle next to an app to view the serial number of the devices the app is assigned to.
Select a device in the list, click the Remove button in the toolbar, then click Revoke.
The app is now available to be assigned to another device.
