I was told by a customer support member through Google Play that I should launch a new topic here about my problem.
I have a brand new 2014 Audi A3 that has Bluetooth. Spotify is able to stream music through Bluetooth without any issues, but on the screen in the car where it normally displays track information, it's just blank. And no, it's not my car, I've thoroughly tested it with other music apps and they've successfully given me all kinds of information about the music. Spotify appears to be the only app for me that is unable to show track information through Bluetooth.
I would absolutely love it if this issue could be looked into and hopefully resolved.
