Guideline 5.1.1 - Legal - Privacy - Data Collection and Storage

I have the issues in this particular guideline: Issue Description

We noticed that the app requires users to register with personal information to purchase In-App Purchase products that are not account based.

Apps cannot require user registration prior to allowing access to app content and features that are not associated specifically to the user. User registration that requires the sharing of personal information must be optional or tied to account-specific functionality.

Next Steps

To resolve this issue, please revise the app to not require users to register before purchasing In-App Purchase products that are not account based. You may explain to the user that registering will enable them to access the purchased content from any of their supported devices and provide them a way to register at any time, if they wish to later extend access to additional devices.

Please note that although guideline 5.1.1 requires an app to make subscription content available to all the supported devices owned by a single user, it is not appropriate to force user registration to meet this requirement; such user registration must be optional.

For this issue, I have revised my app accordingly many times, but it still get rejected even though I believe that I have revised my app accordingly.
