I had been running quick functionality tests every few days to see if Intuit had fixed the problem. I didn't run it on ALL my Customers because there are hundreds and that would be ridiculous. I ran it on the few that I knew had this problem. It appeared to be fixed and I rejoiced. I also stopped the periodic testing because why would I assume that it would work some days and not other? Silly me. Last month's invoices indicated that it is an intermittent issue now. I'll reach back out to Intuit again to try and fix this bug but I'm not optimistic. Though I do appreciate that I am not alone.
