SSO issues

Hello,

I'm having trouble with single sign-on (SSO), before enabling it from the Branding section of the Intune admin center.
Now the SSO setting is not found in the Branding section, and Microsoft Teams, OneDrive, and Outlook are asking users for login and MFA credentials for each.

NB: I have an autopilot issue that I'm addressing, so all devices are out of domain and working as Standalone.

Appreciate your support
