Openid issues with Azure AD

New to discourse, so I apologize if this is something simple I’m missing.

I’m trying to setup OpenId with Azure B2C. Everything is working just fine, but the email address doesn’t get populated in the new user dialog when the authorization is returned. I’m using a standard user flow to manage the sign-up experience, but the claim is returning something labeled as “emails” and it’s a stringcollection, not a single email.

I’m thinking this is a feature specific to Azure B2C, but I’m not sure. Anyone else have this problem?
