The advertisements keep saying that I can go to "discover mode", or "artist mode", and I couldn't figure out how to do that. My friend showed me the drop down menu where you can do that, but my app doesn't have that. I've updated the app and it still doesn't have it. He also doesnt have pandora premium, so I know thats not the issue. Is there a different way to access those features when you're on an older phone?
