Hi again @kolawole
I am sorry about the delayed response to your inquiry!
As far as I have checked on the tenant, as you have stated, it appears that your MFA policy is indeed set to None and you have enabled the option to Customize MFA using Actions.
As far as I have checked in your PostLogin Action Triggers, you appear to have an action named MFA in which you trigger MFA by using api.multifactor.enable('any');.
Could you unbid that specific Action and let me know if that solves the double MFA issue you are experiencing?
Kind Regards,
Nik
