Problem with going to next track on Beta App

[Hawaiianboymw]

The first couple days I had the app I would put a playlist on shuffle and it would go to the next track like normal. Now when a song ends it goes to the next track but there is no audio. If I try to fast forward it goes back to 0:00 and plays again with no audio. The only way is to manually skip to the next track which annoying. I already tried reinstalling but still does the same thing...
