existing Google Workspace users are not directed to Duo SSO

[CharlesTennent]

We set up Duo SSO for Google Workspace.   Authentication is working correctly for new users. When they visit drive.google.com etc they are redirected to Duo's universalPrompt to sign in.  However, existing users that already had access to Google Drive are able to login using the email and password and are bypassing Duo.  

Does anyone know how to correct it?

Thanks

Hmm.. you might need to check the SSO Profile assignments in Google? https://support.google.com/a/answer/12032922?hl=en&ref_topic=7579248&sjid=10070375345509569419-NA#assign_profile

Your question might be better answered by Google.
