We've got the Chromecast with Google TV connected to our TCL TV, and we can't get the YouTube Kids app to appear on the Kid's profile. It shows up and works normally under the adult's profile, but if I switch to the kid's profile, it's not listed in the Manage apps area. I can add YouTube for Android TV, but that's not what we want under the kid's account. It's mind-boggling how confusing this is. We had this working before we had to reset the Chromecast, and now I can't remember what we did to get it to appear!
