Sat there for hours waiting for a book to release. Refreshed for hours and hours and hours. The book didn’t charge to my account even though I preordered it way back on announcement day. Your app doesn’t show the cost of a book or the purchase button on the books store page, for some reason you can only see it on a computer. For years I’ve been struggling with having to switch to a desktop to buy books. After hours and hours and hours trying to refresh to get to my book, I tried my computer and found out the books I preordered didn’t purchase and were sitting there waiting for me to buy again. I’ve been sitting here. Waiting. And your app didn’t even tell me that my order was cancelled AND I couldn’t see that the book was ready for me to buy because your app doesn’t tell you that. Im so unhappy that I’ve been sitting here crying in frustration and I can’t even bring myself to read this book I’ve been waiting on since 2011 now that it’s in my library. What a horrible experience. I don’t care why you don’t have the purchase button in the app and I don’t care why you didn't send me a notification that my preorder was cancelled or didn’t go through, this app is completely ruined for me. Used to be a proud user, now I’m hateful and frustrated and it’s ruined my experience for this book in particular.
