I have Spotify Premium and use my laptop and phone to connect to my Chromecast at home. It works perfectly.
However, since I've added a Sonos speaker in another building, it keeps on showing the Sonos speaker when I'm at home. I doesn't show Chromecast, even though I can still cast to Chromecast from YouTube and other applications.
Okay, I found out. I can press on the three little dots next to the Sonos icon, and select forgetting the device. Would be more logical if that'd happen automatically when you log in on another WiFi though.
Thanks for reaching out and sharing the solution you found with us.
We can also suggest going to the app's Settings and under Devices you can activate ''Show local devices only'' which should get rid of any devices that are not your current network but you you see in the Connect window.
Hope this info helps. We'll be here if you have any other questions.
