Interesting problem, and I need some help.
I have logged in to powerapps.com with my regular ID.
I can choose from the 2 environments at the top right of window.
However, when I click the cog to go to the admin center, it says I need a license.
I have had the Powerapps Plan 1 license for a couple of months now.
I am trying to get in so that I can upgrade the CDS database.
Any advice would be greatly appreciated.
