Removing App Licences

New Contributor

Hi All, I'm currently in the process of replacing a bunch of iPad's for a school. I need to make sure that the licences we have for our apps are removed from the device so they can be assigned to the new ones.

My problem is, several of the apps did not have 'Remove app when MDM profile is removed' when first added to our list of mobile device apps. Will my going through and ticking that box work is is there a more involved process?
