As we haven't heard anything, we’re going to close this for now 🙂/L
Welcome to the Spotify Community.
Do you remember if this started happening after a specific update or event? Also, could you let us know what device, operating system and Spotify version you're using?
We'll see what we can suggest.
Just to confirm, have you checked for updates on the Chromecast's Firmware? Also, let us know if you've ever experienced any similar issue with another app.
You could also try restarting your Internet connection and re-connecting every device to the network. If it's still not working, a clean reinstall might do the trick.
Let us know how it goes.
Thanks for trying @joseravelo,
Let us know if this happens only when you start adding song to the queue, or also when you play from a playlist. Also, let us know if the Repeat or Shuffle options are activated. We'll see what else to suggest.
Is it possible to use a different device to test it? Let us know if you get the same result when managing a queue. If it continues to happen, let us know every piece of info you consider important. It might be worthy to report this.
Thanks for letting us know.
Could you let us know the exact Firmware on your Chromecast device? We'd recommend connecting to another WiFi network and let us know how it goes.
Take care 🙂
