My Question or Issue

 When using the "Listen on another Device" function to use my Mobilephone to Play/Pause Spotify on my computer the mobilephone also plays the music I am listening to on my PC. 
But with a delay of about 2 seconds. 

So all I get using my mobilephone as a "remote" is that I hear the song playing on the phone AND playing on my PC, but offset by about 2 seconds.

So this function is useless at the moment and more prone to create headaches than joy.
