Cannot assign application to user flow in External (B2C) Tenant

Hello,

I've set up a registered application (which is working) on my B2C Tenant. I wanted to assign that application to one of the user flows I created.

I was following this guide: https://learn.microsoft.com/en-us/entra/external-id/customers/concept-planning-your-solution

It makes me register the application in the B2C Tenant (fine, sounds good to me) but makes me assign the application to the user flow in the Workforce Tenant. I follow those steps but when I try to add the application I cannot find the registered application, because I registered it in the External tenant. Moreover, if I try to create a user flow in the B2C tenant I can't see the "Use" section with the "Applications" option:

User's image

Can you help me fix this issue? Thanks!

    Hi @Filippo Iacobellis ,

    The application should be assigned to the user flow in the external tenant. The tenant configuration article says, > The external tenant is where you'll register your apps, create sign-up and sign-in user flows, and manage the users of your apps.

    I believe what you are describing is expected behavior and you need to add the user flow in the external tenant. If I missed something though, please feel free to share the section of the article you're referring to and I will get clarity on it.

    If the information helped you, please accept the answer. This will help us and improve discoverability for others in the community who may be researching similar questions.
