Our client is using QB 2023 Accountant Desktop.  Webmail has been successfully configured to use Gmail with enhanced security.  Both the Intuit and Gmail security logins have been entered successfully.  She is intermittently receiving the "unable to send emails due to network connection failure" error.  Sometimes the form gets sent with a second attempt, sometimes it does not send at all, regardless of the attempts.  The intermittent nature of this error suggests it's something on the Intuit side.  Please advise.
