Should have searched the community first. Social/enterprise logins don’t count trigger actions as per this thread:
https://community.auth0.com/t/post-user-registration-trigger-for-actions-not-called/70262/3
I do wish this counted as registration since a new member is created in the “User Management” tab in Auth0. Is there a technical or user requirement reason why it’s not?
Please mark this thread as resolved. Thanks everyone.
