Azure B2C - Custom User Flow for Phone Sign Up - Not persisiting Extension attributes

Hi,

I am trying to embed the Terms of Consent page in the Phone Sign Up Custom User Flows, everything is working fine except that the Terms of Consent Page comes up always even if the user already agreed to it. I implemented this in Email Sign Up Custom User Flow and things work exactly as expected there, but having trouble with Phone Sign Up Flows.

Blog I am referring to implement this : https://justidm.wordpress.com/2018/10/01/add-a-terms-of-use-consent-page-to-azure-ad-b2c-user-journey-with-custom-policies/

Above blog refers to implement in EmailSignUP Custom User Flow , and it works fine for me there, but I tried same concept in Phone Sign Up Custom User Flow but it seems that ReadUserWithObjectID step is not working the way it should. Ideally it should persist the TermsofConsent extension attribute once and next time user signs in should match the criteria and NOT bring up that page again. But in my case, it always brings up consent page no matter if user already agreed to that at the first time.
