SignIn with Apple: Primary App Id of Service ID

Hi,

I'm trying to implement web-browser SignIn with Apple with my new app. I'm trying to "Associate your website to your app" like described in this doc: https://developer.apple.com/help/account/capabilities/configure-sign-in-with-apple-for-the-web So I created a Service ID for this specific login. I want this login page to display my app icon and name when presented to users.

My issue:

When I associate my new app the the service, the link is somehow not working. The login page show the "service" login (with a generic apple logo and the Service ID's name) instead of the actual App name.

I'v been able to link my new service to older apps succesfully !!! (the login page correctly shows the old apps icons and names)

Why is my new app not associated with the service ?

I am missing something here ? is there an additionnal step that I need to take in order to link the service to my newest app ?

Thanks !
