I am trying to connect Spotify to my Yamaha RX-A830 AV receiver but it is not visible in the Spotify App anymore. Been using it for 5 years but suddenly it stopped working (few weeks ago). I have a Spotify Premium account, Spotify app on my Iphone 8 is updated as is the firmware in Yamaha. Yamaha is connected to internet in the same network. Does anybody know the reason for this or how to fix it?
