Note 5 spotify not working. help :(

[Gamerboy]

I recently got a note 5 and have been using spotify with it for about a week now but it isn't working at all. Whenever I close the app the widget that should show up when u pull down the screen doesn't but the music keeps playing and everything and in order for me to stop it out have to reopen the app and pause it. Same thing goes for the lock screen the widget doesn't show up so I have to unlock my phone and open the app to change the music or pause it.
