Azure B2C SMS OTP Verification with Custom Display Control

Question

I'm currently working through a couple of situations here...

1. Where the current OTP functionality for SMS that I have does not auto submit the verification code when using an IPhone (paste functionality). I'm trying to add a "Verify" button on that screen to enable the users to be able to submit, liberating this lack in functionality.

2. using a custom display control to only show the US country code.

I am still seeing the default of all country codes and there is no button populating... I'm not sure what I'm missing here.

please find the components of the policy below...

    <ClaimType Id="countryCode">
            <DisplayName>Country</DisplayName>

            <UserInputType>DropdownSingleSelect</UserInputType>
            <Restriction>
                <Enumeration Text="United States (+1)" Value="US" />
            </Restriction>
        </ClaimType>

Answer 1

1. For the verify button to show up, update the version in DataUri property of ContentDefinition.

     <ContentDefinition Id="api.phonefactor">
       ... 
       <DataUri>urn:com:microsoft:aad:b2c:elements:contract:multifactor:1.2.5</DataUri>
       ...
     </ContentDefinition>

2. If you are planning to use display controls instead, I believe you need to use a Self Asserted technical profile instead of PhoneFactor one. Ensure you use a new version of selfAsserted page (Update DataUri in ContentDefinition). eg: 2.1.6.
