CSOM AuthenticationManager doesn't ask for sms-code or authenticator

I have implemented the authentication flow using AuthenticationManager in a Windows Forms app using CSOM. Works very good and supports MFA as it should, except for in one tenant (so far). In that tenant it starts the flow:

  1. Opens the window and asks for username.
  2. Switch to password window.
  3. Blank window ( here it should ask for the sms-code sent to the mobile device).

Works in other tenants. Maybe some kind of policy that applies but I have tried to recreate the error with no luck. Any suggestions?
