A registration completion screen in web screen-sets is triggered in the following scenarios:
* Missing Mandatory Field: When a user registers via a social network and a mandatory field required by the site is missing, the registration completion screen prompts the user to fill in the missing information.
* Expired Terms of Service Consent: If the terms of service consent record for a customer has expired, the system will require the user to re-consent, thus triggering the registration completion screen.
These scenarios ensure that the user provides all necessary information and consents required for compliance and proper account setup.
