I have Googe's Chromecast, my model is the NC2 6A5, and after setting it up, updating the firmware, and all that stuff, it works perfectly with all my apps but spotify. The exact issue is the little "Spotify Connect" button in the now playing screen not showing up. When I go to settings and tap on Connect, the device list is empty. I have a Moto g3, with Android 5.1.1. and the latest version of the Spotify app as of today. Other devices (such as my computer with Spotify desktop running on it) do show up and work. I'd appreciate any help, thanks.
