I've noticed an issue with the BlueTooth track information when using my phone in my car.
If I have my car start Spotify playback, Spotify wil play from the correct song / position. It will send the track information for this song. However, as it continues to play other tracks, it will not update the track information, so it will constantly show that first track.
This does not happen if I start playback from the phone instead. It does not happen if the Spotify notification is still present in my notification area when I start playing from the car (this notification disappears after a period of inactivity). Once it occurs,I can only fix it by closing Spotify (which I do using the X on the notification that is now present) and starting it again, then starting playback from the phone. If I just pause the song on the phone and start it again, the issue does not resolve itself.
