No luck here. My partner tried creating a ticket with Microsoft, but was told that they needed to talk to the "Technical Support Team".
My partner does not expect that they will get anywhere with a ticket to that team and said I'd have to pay the hourly rate for them to continue pursuing this. I can't afford that right now, but may re-visit in the future.
My guess is that sometime in the last year, someone in the Licensing department clicked the wrong button--unknowingly removing something that was there by-design. Hopefully someone else will pick this up and try to get Microsoft's attention.
If anyone wants more details in order to take this to Microsoft, please reach out. I keep all my old license files and license details.
