Exact same issue happened to me. Quickbooks 2020 desktop. I use gmail in quickbooks. The so call work around  doesnt work. How do I reach the support team. Its not via these useless forums, is it? This software should be sold with the customer service number in bold on the package. I just got my bankfeeds to work yesterday now it will not send an email. I have read enough forums to create a liberal arts program and they have been just as useful as one. This is the  money that keeps my family and business and I regret my purchase deeply.
