Great app but has a bug

I really really like this app and I use it all the time! The only problem is sometimes when Im listening in the chapter switches the app seems to pause or glitch and it wont play anything for a day or two. Sometimes when I go to open the app and play a book it wont even start it just sits there on play the timer doesnt run, just silence. Ive tried deleting all my books and re-downloading the app but that only fixes it for a day or two until the same thing happens again. Ive tried using other audiobook apps but I always come back to this one because it has such a great variety of classic books. Please fix the bug!!
