Does not show my MP3's – Cloud Music Player - Listener Review

I connected my Google Drive account where I house the tracks I want to stream. I got this app to create a playlist, but it will not even show me the MP3's from my Google Drive so I can load them. It shows the existing FOLDERS, but not the contents of those folders. I'm confused about this issue, because there are so many positive reviews. Grrrr!
