Chromecast has an overall buggy experience. The worst one is that playback randomly pauses while casting.
These "fixed" (not actually fixed) issues are related:
Overall the Chromecast experience seems like an after-thought. I am tempted to switch to Google Music but I would much rather support Spotify.
Please give Chromecast the support it needs. We just want to play our music without it stopping randomly. Netflix doesn't do this, YouTube doesn't do this, this problem is unique to the Spotify app.
Agents have been unhelpful in linking me to Chromecast support: I do not have a problem connecting so that suggestion is not helpful.
Uninstalling the app and resetting my Wifi doesn't help.
Please forward to your engineering team.
