I also am having the same problem with Quickbooks 2020 for Mac. I cannot email my statements as I have for years. This is my 5th version of QB and I am extremely frustrated. Will I be wasting my time if I can even get through to customer support. I have tried everything that I have read in these comments. I too want to continue to have these emails sent to my draft folder for further editing. Right now i get the same error everyone else is getting and nothing shows up in automation to select to allow control. Does not work on default or custom email.
