Notification bar gone when paused

[ReasonableCheff]

I have a note 5. Before, whenever I paused a song, the notification bar would stay so I could un pause the song. Two days ago, whenever I paused a song, the notification bar would disappear and would only reappear when I went into the app and unpause it instead of using the notification bar. I reinstalled the app and was wondering what happened. I have android 6.0.1 now and updated around 5 days ago.
