The TV has built-in Chromecast and I can cast screen and YouTube videos on it from my phone. But I can't play anything from the Google Home Mini - neither on YouTube nor on Google Play Music. When asked, the assistant says it's playing the video/music on KDL-50W800C, but nothing appears on the TV screen whatsoever. The Home app on the phone shows both the TV and Home Mini and both are connected to the same wireless network. I'm totally at my wit's end now. Any help on this matter will be much appreciated.
