Power BI Pro License

Hi  DANIELDDAB 

Each free user can apply for a trial version of the PPU (Premium Per User) license after applying for an account and logging in to Power BI Service. It has no conflict with the Pro license you purchased yourself. The trial version has a 60-day trial period, once the trial period is over, you need to purchase it again. If you have created a workspace with PPU license, the content of the workspace will not be accessible after the PPU license expires. You need to renew the PPU license, of course, if you didn't use PPU license to create the content, then even if the PPU license expires, it has no effect on your Service. All you have to do is turn off the pop-ups.

The PPU and Pro belong to two different licenses, if you are interested in the PPU license, you can learn about it in the link.
