We recently upgraded our living room TV from a Chromecast Ultra to a Chromecast 4K with Google TV.

When trying various Assistant commands on the rest of our Google Home devices targeting the new Google TV device (named Living Room TV), it always understands the command, and then says "Sorry, I don't understand." I can look in my Google Home history and I know it understood it correctly.

For example: "Play Seinfeld from Netflix on Living Room TV," has been a command we were always able to successfully use with the old Ultra. Now, it says "Okay, playing Seinfeld from Netflix on Living Room TV. (pause) Sorry, I don't understand."

The same command works just fine when I try to play it on any other Chromecast in the house (bedroom TV, Hub Max, etc). It's specifically only having issues on this Google TV device.

I tried changing the name of the Google TV device in case it was somehow conflicting with the old Chromecast, but it still doesn't work.

Anyone know what gives? I've rebooted (but not removed/re-added) this and all other Chromecast and Home devices.
