[Beta] Customizing sender domain

My app correctly sends emails from the custom domain, but this page shows a different domain and the button that allows to check and modify the configuration doesn’t work.

  • The button does nothing - this is clearly a bug
    The app id is included in the default sender domain instead of the configured custom domain - I think this is wrong, or at least incomplete and confusing

I would like for the button to work and for the description to include the custom domain already configured.
