FYI, the only reports that are not working for the files that I have transitioned from 2018 to 2021 are the memorized reports that I have used just recently.  Reports that I created last year or before are available.

Perhaps this will help narrow down the problem for QB Tech Supt.

This is a real problem for my clients as we do job costing and work from memorized reports for our projects.

And for all my clients we are converting from 2018 because our payroll subscriptions will not work without the updated software.

RRRRRRR!
