CYC...greatly appreciate the information unfortunately the issue we have is that when using the "Projects" functionality for our customers, the email addresses on any new invoices do not reflect the email addresses outlined in the actual Customer profile. 

The email address when building invoices for any "Project" will not reflect any updated email addresses entered under the Customer profile and in most cases, the email address on the new invoice  will only reflect a single email address which is the 1st email address outlined within that customer profile.  If there are multiple email address (a 2nd or 3rd), then they do not correctly populate on the new invoice.

If you are NOT using the "Projects" feature for your Clients, there are not issues as this software issue is only impacting the "Projects" invoices.

Thanks for trying to assist!!!
