This is the most frustrating app on my phone. It crashes in a number of different ways. Most frustratingly, it refuses to play downloaded content when I'm away from Wi-Fi or data, which is exactly the reason I downloaded it. They will throw different page looks at me from time to time so that I have to go digging around to find what I want. Often I have to dismiss some nonsense before I can actually get into the app. It is also unclear about why some downloaded content becomes undownloaded
