I'm not having the same issue on desktop, but since I like to practice listening when outside I hope my phone can have the same functionality.
Whenever I try to play an audio track on my phone, either by double click or by clicking the play button, the number of times I've played the track does jump up by one, but the track itself doesn't play. The information on the bottom of the screen also says it's a track of 0 seconds, but again, the desktop version can just play the full file, no problem.
