I see you’ve been through a lot getting things as they should be, B3BS.

I can share some details about the ProAdvisor Certification program in QuickBooks Desktop.

Generally, we release the QuickBooks Desktop certification course once every year.

The exam from the previous year is still accessible for a few months after the introduction of the new version. The data will be unavailable if there's incomplete progress you've made on an exam or its training modules.

If you wish to add materials for QuickBooks Desktop, you would need to have a QuickBooks Desktop ProAdvisor membership. On top of that, you'll get a free license for the bundled software of your choice.

If you avail of the ProAdvisor bundle, there's no additional charge. 

I've added this link for an overview of your current QuickBooks Desktop 2022: An exclusive QuickBooks ProAdvisor price.
