External Users Unable to Access SharePoint. Now prompted to use Microsoft Authenticator. Not needed.

[Muyiwa65]

Some of our SharePoint users are unable to login. Upon attempting login, they get a message stating "More Information Required" PLEASE HELP! Upon clicking "Next", they get a prompt for the MS Authenticator app. Our organization does not need this additional 2-factor authentication step. Please help.

You need to reach AAD admin and check New/old policy changes.
