I have a Windows 10 pc running a newly reinstalled Spotify that does not allow me to connect to my other devices. My Spotify app on my iPhone can stream to my chromecast. All devices are on the same WiFi network.
As of now, Spotify connect has to start Spotify for Chromecast from a mobile device or touchpad. Once Spotify is started on your Chromecast, you can control it from your computer!
