New ProSeries Customer – Unable to Complete Primary Firm Administrator Setup

I am a new ProSeries Professional customer and installed ProSeries 2025 today. The installation, licensing, product updates, and connection to my Intuit account were all completed successfully.

However, I cannot complete the initial Primary Firm Administrator setup. When I select “Set up my firm,” I am taken to Manage Users. I check the box certifying that I am the Primary Administrator and click “Get Started.”

Every time I do this, I receive:

“Unfortunately our systems are currently experiencing some issues. Please try again later.”

I have tried multiple times, including directly through the MyProConnect website, with the same result.

Has anyone encountered this with a newly activated ProSeries account? Is there another way to complete the initial Primary Administrator setup, or does Intuit Support need to provision/reset the Primary Administrator on the account?

At this point I cannot complete the setup and access ProSeries.
