@Fabry Doug Thanks for posting in our Q&A. For this issue, it is not related to windows 365. It is related to Microsoft license.
Honestly, I'm not familiar with this. I have done a lot of research, did you want to make it via Power App portal?

If yes, I think there is no any other cost, because the Power Apps are included in 365 enterprise F3 Subscription.
To get accurate help, it is suggested to contact Licensing support. Here is the support link:

Or please call Global Customer Service phone numbers to find the support.
Thanks for understanding.
