Browser Not Secure error when trying to set up Gmail with enhanced security to send from Quickbooks Desktop 2018
When I follow the guide to use enhanced security for gmail (web mail for invoices), a webmail authorization window is opened. When I click "Next" and get the message that the browser or app may not be secure (and Couldn't Sign You In). It suggests using a different browser,, but the window is opened by QB. It is a QB window.
I am using the procedure to Set up secure webmail. https://quickbooks.intuit.com/learn-support/en-us/configure-products/connect-your-email-to-quickbooks-desktop/00/201268
What do I need to do?
