Dynamics 365 Enterprise licenses does not include general purpose Power Apps capabilities. Dynamics 365 Enterprise users will continue to be able to run apps and portals that extend and customize the licensed Dynamics 365 application, as long as those apps and portals are located in the same environment as their licensed Dynamics 365 application.
