"If your iPad app offers subscriptions, you likely want to promote your newest content and display purchasing options clearly. To help with this, new v31 iPad subscription apps have new default library with a new appearance to help promote your content. The most recent folio will have a prominent presentation to help encourage readers to identify the newest content available for purchase or subscription. If a free preview of content is offered, that’s called out too."

We do have subscription.
How to enable "Folio Showcase in Library"?
