Looks like my last post was a little premature, as overnight we received emails like the above for Apple School Manager.
Like the Apple Business Manager email received beforehand, this email forewarns of a change to the Apple School Manager terms on December 3, 2020.
This time, however, the email was from a more expected address (email@example.com), and the email contained no link to the terms for review beforehand.
Digging around though, the PDF may possibly be found here.
Anyway, if you are an Administrator of an Apple School Manager instance mark down a little task on December 3, 2020 to approve these new terms.
If you don’t agree to the terms in a timely manner, you’re likely to see issues with ADE/DEP as detailed previously.
