Hello, I just installed official google app called android tv launcher on android tv box, play store says uninstall instead of install which means it is already insalled but it doesn't make sense. Not activated there is nothing about it, it isn't showing in the apps nor homepage, app isn't seen anywhere, nor activated what can I do? How should I activate this launcher?
