I'm using a MacBook Pro (2016 with touch-bar) running macOS High Sierra (10.13.3). With spotify running in the background, I'm able to see an icon for opening Spotify options (screenshot 1) - but it vanishes sometimes and I have no idea on how to get it back (screenshot 2).
From screenshot 1, if I touch the spotify icon, I see a scrub bar without an indication of where in the song I currently am. If it does show up, it's at the end of the bar. I find that I'm able to scrub by dragging the pointer to somewhere in the middle but it's quite inaccurate and hard to tell where it will stop at.
I've tried reinstalling Spotify but with the same result. Not sure how to fix this, any help is appreciated.
