Multi-session reverting to single-session mode - Windows 10 Enterprise multi-session 1909

[Davidj840]

I am using the "Windows 10 Enterprise multi-session, Version 1909 + Microsoft 365 Apps" image and verify that the ProductType is 3
{{Get-WmiObject Win32_OperatingSystem | select ProductType}}
but then something happens at a point during post-deployment manual tasks that reverts this back to ProductType 1 and you loose multi-session capabilities.
Could it be a license thing?

Could it be a windows activation license issue whereby we do not have the requried licnese for multi-session?

This can happen if you manually apply activation key that subsequently changes the product type. Can you please make sure that your post deployment tasks do not contain any activation automation.
