On my ZTE Axon 7 phone as well as Samsung Tab S2 both using Android 6.0.1 and latest Spotify app the Now Playing bar that allows you to skip and pause dissappears whenever the screen turns off or if I switch to other applications. It does not come back unless I totally shut down Spotify. This is a consistent issue since the newest software update. I generally am casting to Chromecast audio and can pause from the Google "Home" app, but not change songs.
I have re-installed, rebooted numerous times.but the issue comes back. Not sure if it only happens on ChromcastAudio. Any solutions?
