Needs improvement

With the new update, I can no longer use the books in my iBooks app. They just dont appear. How am I supposed to read the books now? I wish the app had the ability to upgrade or enter a code at checkout when buying the books or something to be able to see the books in the app. Because right now, its pointless to me. I would really like if I were to be able to read the books Ive purchased, on the app. Also, I cant seem to understand Instagram, so I would like to communicate with other people in my journey. Make it in groups, that way people can grow together in their journey. I really hope they make some very needed improvements.
