I have requested refunds for my clients who are reporting being affected by this issue and Quickbooks has given me a credit note - I will pass on the refund. Suggest you guys also request refunds. the time you are being effectively required to spend checking all invoices to see if they've been received  is unworkable. If a fix doesn't happen within a month, we will have to move software. We cannot keep supply a product that doesn't work.

I just got an email about a the new Quickbooks Advanced  product being rolled out - assume thats what all their engineers have been working on. Maybe they will now be free to fix the products they already have.
