Im rejected my app twice. my app allows users to download and view books purchased on the website. (website is our company's) but apple rejected app cause "We still noticed in our review that your app allows users to access previously purchased books content or content subscriptions. However, your app includes an account registration feature for paid content.
Guidelines 3.1.1
"Reader" apps are apps that access certain kinds of previously purchased digital media. They may offer account creation for free tiers, and account management functionality for existing customers, but they shouldn't include registration for accounts that access paid content."
What should I do about this feedback?
