So I just bought a TCL TV with Android TV built in, which has been excellent so far. However, I'm unable to use my Google Home Mini to play content with the built-in Chromecast. When I ask it to do stuff (play music on Spotify, play content on Netflix) it says that it can't find the device name on the network. Manually casting to the TV works fine. When I plug in my old Chromecast to the HDMI port the Home Mini has no trouble casting to that either. Is this a known limitation of Android TV/TCL or have I configured something wrong?
It's a know limitation sadly. The TV has Google cast not the full Chromecast suite. Allegedly Assistant was supposed to fix all this but as of yet nothing.
