Welcome to the Community, @PHIL SYKORA. I'm here to share some details about the discontinuation of QuickBooks Desktop (QBDT) services and certification.

The QBDT add-on services will be discontinued after May 31, 2022. That means the latest security patches, updates, payroll, and support services will be discontinued. 

I've added an article for your reference: QuickBooks Desktop service discontinuation policy and upgrade information.

In addition, QBDT Advanced Certification training modules and exams has been discontinued effective last December 31, 2018. Certified users will continue to have the Advanced Certification status extended for three years.

The extension started in January 2019 and will remain active until January 1, 2022. For more information, please visit this article: ProAdvisor Certification FAQs.

Please don't hesitate to comment below if you have any concerns or questions about ProAdvisor Certification. I'll be sure to get back to you.
