ListenBook Pro funktioniert nicht

Therefore, I did my best to make ListenBook a tool that has everything necessary to make this process intuitive and convenient. • Plays audiobooks in MP3, MP4, OPUS, OGG, FLAC, AWB, M4B, M4A, WMA, AAC formats (without DRM protection). • The book cover is loaded from an image file in the book’s folder or from an embedded image from an audio file. • Automatically saves the current playback position for all audiobooks. • Jump to any file (can be enabled in settings). • Playback control from the Control Center and Block screen. • A sleep timer with adjustable sleep periods or sleep after the end of the current chapter.  ListenBook is the easiest and most convenient app for listening to audiobooks in MP3, MP4, OPUS, OGG, FLAC, AWB, M4B, M4A, WMA, AAC formats on your iPhone, iPod Touch or iPad!  The purpose of this app is to make listening to audiobooks in different formats easy and convenient!  Most of such audiobooks are distributed as folders with multiple audiofiles in different formats.  There are lots of websites with all kinds of audiobooks dubbed by professional actors and enthusiasts.  I'm, the author of the app, listen to audiobooks all the time.  If you enjoy ListenBook, we would be glad if you consider writing a review.
