As part of the planned transition from the Power Apps and Power Automate admin centers to the Power Platform admin center, all admin operations and associated cmdlets have been migrated to Windows PowerShell. With this change, admins have the capability to export a list of assigned Power Apps and Power Automate user licenses by performing administration operations using the admin cmdlets.
How does this affect me?
There is no option to download the list directly from the Power Platform admin center. Instead, you will need to install PowerShell to perform operations using the associated admin cmdlets.
For more detailed instructions on how to do this, see here.
