I am not able to find a Microsoft link documenting the features comparison matrix between Azure AD B2C P1 and P2 . This is the only link I could find. My assumption is that if I want to do a quick estimate on MFA (based on risk based scenarios) costing with Azure AD B2C I would have to use the P2 MAU pricing model along with MFA events (cost for sms / phone events). Could someone confirm my understanding ?
