Hi Rob_Pasell , this upcoming change does not affect scenarios requiring MFA during Setup Assistant with modern authentication and will continue to function the same with the modern auth enrollment method; users will either need a second device or Temporary Access Pass (TAP) to complete their authentication and registration flow if MFA is configured. Additionally, you will still be able to send down the Company Portal as a required app with the attached app config if you choose to do so, replicating the same experience that Setup Assistant has currently, before this change. We appreciate your feedback and we’re sorry about your recent support experience. Feel free to private message @Intune_Support_Team your support request, so that they can investigate this further with our support team. Thanks!
