I have been using this app for the last few years  and it's a great one. The scaled down interface is wonderful! I'm downrating it just to let the developer know that there is an issue that has started since the last update. Audiobook files will only play for three minutes at a time before stopping suddenly. This continues every time you pause and un pause. It has gotten very annoying and I very much hope you fix this error!
