I'm having the same thing, does anyone know why it's not appearing? How can I determine that my subscription is working properly in production if I'm not using a server and App Store Connect doesn't show subscription information?

It seems you have a good understanding of the different UI elements. Like you said, you would use two UITextFields in order to allow the user to input their username/password. In order to directly answer your first question: There is no standard way of implementing a login screen in an app, but here is a link to many examples of some: pttrns.com/?scid=17 Most of the time there’s no need to create a new window for this, in general you shouldn’t have interaction with the app’s window. Lastly, it is important to note that if you are implementing a sign up/log in system, and it will have social media login options, you must comply with App Store Review Guideline 4.8: https://developer.apple.com/app-store/review/guidelines/#sign-in-with-apple

I am also having this issue 😟, have you come up with a workaround?
