License is downgraded repeatedly

Question

Hybrid Azure/AD environment. Windows 10 Enterprise license is being downgraded to Pro on some devices. Devices ship with Home license, and are rebuilt using corporate Enterprise build via WDS.
Devices lose network connectivity for a few seconds, and license is downgraded to Pro. This can happen several times daily.
One device was licensed using corporate Enterprise MAK code and was downgraded to Pro inside 2 hours ruling out KMS as point of failure.
No errors re events 12288-12290 in application logs

Answer 1

An issue has been identified with Hybrid Azure AD joined devices that have enabled multi-factor authentication (MFA). If a user signs into a device using their Active Directory account and MFA is enabled, the device will not successfully upgrade to their Windows Enterprise subscription.
To resolve this issue:
If the device is running Windows 10, version 1703, 1709, or 1803, the user must either sign in with an Azure AD account, or you must disable MFA for this user during the 30-day polling period and renewal.
If the device is running Windows 10, version 1809 or later:
Windows 10, version 1809 must be updated with KB4497934. Later versions of Windows 10 automatically include this patch.
When the user signs in on a Hybrid Azure AD joined device with MFA enabled, a notification will indicate that there is a problem. Click the notification and then click Fix now to step through the subscription activation process

No notification in these cases.
It would appear the same issue in https://learn.microsoft.com/en-us/answers/questions/29465/windows-10-professional-hybrid-azure-ad-joined-wil.html was never resolved.
