I am having the same issue as other with PC version of Quickbooks Desktop 2020. I have I have been using the software for a number of years and never had this problem until a few months ago. I have talked to tech support with Intuit, my email provider (Godaddy) and computer security, McAfee LiveSafe as late as today to no avail. I have switched browsers from Google Chrome to Microsoft Edge to Firefox, all with the same issue. I have turned off my firewall, added the specific websites to my browsers and reduced the security to its lowest level, again to no avail. Can someone from Intuit please help with this issue? It is causing a major issue with my invoicing process
