My TV with Chromecast TV built-in is visible on the Google Home App under "Other Cast Devices", but I can not manage it like other connected devices, for example I cannot move it to a specific room.
Also it disappears if I'm not using the Home App connected to the same WiFi network, which I think is because is not really added to the Home App, but only linked to my Google account.
There's no way to add the TV as a device like when you add a speaker for example, it doesn't get detected.
I'm logged in in the TV with the same Google account that I'm using for the Home App.
In the images you can see that there are not options to configure, remove or unlink the TV to do a reset from the Home App.
Any clue of how to solve it? I'd like not to reset the TV to factory settings.
