So, ADE is not affected by this 🙂
You can enroll Apple devices with either Device Enrollment or User Enrollment. And both works (for now) for Account-Driven or Profile-Drive. That leaves us with ADDE, ADUE, PDDE and PDUE 🙂
The old "normal" way of doing enrollment is "Device Enrollment" so most likely you're not affected 🙂
If users go to https://dsxxxxx.awmdm.com/enroll or enroll through Hub app, then you're using Profile-Driven Device Enrollment (PDDE - Not affected).
If your users go to Settings, VPN & Device Management and login, then they are using ADUE (not affected).
If your users go to https://dsxxxxx.awmdm.com/enroll/user/ you're using PDUE (Affected)
I hope this answers your question 🙂
