Since I updated the Spotify app on Windows Phone 8, I can no longer see the progress of the song on my display in the car.
It just shows 00:00 as start time and no end time.
This morning however, it started showing the progress of the song but the information was incorrect.
It showed that the song was 50 minutes long while it was just more then 3 minutes long.
Other apps, like the new podcast app on Windows Phone, show this information correctly.
The reason I mention this is because I use the Windows Phone 8.1 developer preview.
