We noticed that your app requires users to register with personal information to purchase non account-based in-app purchase products, which does not comply with the App Store Review Guidelines.
Apps cannot require user registration prior to allowing access to app content and features that are not associated specifically to the user.
Next Steps
User registration that requires the sharing of personal information must be optional or tied to account-specific functionality.
To resolve this issue, please make it clear to the user that registering will enable them to access the content from any of their iOS devices and provide them a way to register at any time, if they wish to later extend access to additional iOS devices.
Please note that although guideline 3.1.2 of the App Store Review Guidelines requires an app to make subscription content available to all the iOS devices owned by a single user, it is not appropriate to force user registration to meet this requirement; such user registration must be made optional.
