This is my favorite app. I use it more than every other app on my phone, at least I used to. For the last 6-8 months, the app doesn't work. I can only listen to the book if the screen is on and the phone is unlocked. Otherwise, it will shut off. I even got a new phone in this time, excited to see if it would improve. It didn't. I have started looking for options for the first time ever. So disappointing. Think carefully before building up a nice library on this app, you may not be able to enjoy
