Cortana does not recognise "play next track", "play next" or "skip track" commands for Spotify on my PC (Spotify integration with Cortana is otherwise working fine).
If I'm missing a setting it doesn't seem obvious, but please let me know if there is a way to instruct Cortana to play the next track on Spotify. If not, then come on Microsoft/Spotify, this is an absolute basic necessity! Put your act in order please, it cannot be difficult - even my 2010 car radio can skip tracks by voice... I am thinking of purchasing yet another Alexa for my PC just to get round this, which seems crazy.
