Ch21: Page 562 Registering the app

I seem to have problems with this each time I work with a new app. My understanding is that you need to get an App ID before registering on iTunes Connect. I did this through Developer Center:Account:Login. Then Certificates, IDs, Profiles: App IDs. After adding (+) a new App ID I had to log out and back in for the bundle ID to show in the next section on page 562-3.
