I receive this when submitting an app for review:
Please note that although guideline 11.6 of the App Store Review Guidelines requires an application 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.
However, is there any suggestion if user registration is not required but can allow a single user to access subscription content in other iOS device?
How the app can identify it is the same user?
Thank you very much!
