I signed up for a Get started free 60-day trial of Power BI Pro.
After the licence expired I want to upgrade the account and buy a licence but
I went to the site https://portal.office.com and logged in.
But I get the message:
You can't revoke permission because this has been assigned to you as part of a subscription or an admin role.
My question is how can I get admin role to create the subscription.
The only person in the organization is me and no one else.
