I have an azure b2c instance with 1 user flow making use of "Sign up v2".
when I have javascript turned on, a custom idp selection page and a custom local account signup page the sequence fails. if javascript is off, or i use either of the built in pages it works.
the failure is that the body of the local signup age is not filled in (the email, password, etc boxes are missing).
the most interesting thing I can find out about this is the url's are different in the fail case & I cannot find an explanation for that. specifically, in the fail case the url is in the format:
https://<customer page host name>/<tenant name>.onmicrosoft.com/B2C_1_signup/api/ClaimsProviderSelection/selected?accountId=SignUpWithLogonEmailExchange
in the success case it goes to b2clogin with the format:
https://<tenant name>.b2clogin.com/<tenant name>.onmicrosoft.com/B2C_1_signup/api/ClaimsProviderSelection/selected?accountId=SignUpWithLogonEmailExchange
thoughts?
