This fixes the issue for estimates except that I don't want "online delivery" of invoices due to issues we have had with online delivery. I can only select online delivery for both estimates and invoices in the settings. I want to be able to just email a pdf attachment from Quickbooks like I had been doing for several years. I have no other choice but to attach the pdf estimate to my own email and send from there instead of the much faster way to send from Quickbooks like I had been doing for many years. It looks like this is an option that is not returning. Thank you for your help but this fix won't work for me unfortunately since I don't want online delivery of invoices.
