Actual requirement is to perform a PoC and Impact Analysis for setting up a Designated Power Platform Environment for the SharePoint list customized with Power Apps forms.
Client has created a E5 trail Tenant and when I tried and couldn't create a Power Platform Production Environment due to Database Capacity not available.
To proceed further, I started to explore, how to get extra DB capacity and one straight forward option is to procure Dataverse Capacity add-on of 1 GB. while other option was to go for any Base License like PowerApps or Dynamics 365.
As I am currently working on Power Apps, my idea was to go for a Power Apps premium license (per user), where I could find to different opinions that this enables 20GB default Capacity and then 250 MB per user/month license and few says it only give Default (3GB) + 250 MB per user/month license.
Need help to clarify which option in correct like for initial purchase of Power Apps Premium (Per User) license, it enables 20 GB + 250 MB = 20.25 GB Database Capacity
or it enables only Default base capacity (3GB) + 250 MB = 3.25 GB capacity
