You probably already have it in your library. The showcase library will only *show* one page even though there are probably many. Hit the left and right arrows by the page number (which will only show 1) to flip through the pages.
@RatlleRo it's probably already in your library. In the Showcase section, although it won't show it, there are multiple pages. Click the right single arrow to go through them. Mine was on page 4.
You're right, I already have it. I thought I had checked, but it appeared I only had 1 page in my showcase. I had multiple pages, the UI just doesn't show them.
