I am having the same issue and it has become a huge problem.  Please advise as to how to fix this.  My "Message to Customer" is no longer showing up on invoices that are emailed and paid through Quickbooks.  If I download them and email directly the information is there.  What can I do?

I tried to contact customer services but it says they are unavailable until Wednesday which is tomorrow.  Not sure why they aren't open today.
