My Question or Issue
It's just a few days, my Spotify "quick panel" buttons (play-pause, ff and back) are disappeared. I refer to that little panel that opens when you mouse over the tray button of Spotify. It was extremely useful, it's a chore to click and open up spotify every time you want to pause, skip, etc.. 
On my side I did nothing, except pairing the app on a new android cellphone (before, I had a WindowsPhone).
How can I solve this? thanks in advance.
