Lacerte Users Reporting Multi-Factor Authentication Code Not Being Received

@IntuitGabi The other post about this problem says SOLVED. I can't find the solution.

@IntuitEric This failure of the MFA system shows vividly that certain customers do not need MFA.  Sole proprietors with no public office, with no employees, living alone, with effective Windows operating system security measures in place don't have outside threats to their Lacerte access.  Such people have a risk of about .00001%.
