I think you have to enable to apps to be searchable with Google TV... I recall doing this on mine after setup.
Google TV is just not that good. It's like a cute idea but mostly unnecessary and only slightly useful. I've already replaced it with a 3rd party launcher.
Am I missing something here? Don't you have the apps for your streaming services? 🤷🏽♂️
First of all, it could be a country issue.
Second, is the your streaming services added to Google TV? You can check them in settings> accounts & sign in> your services
Third, Go to settings> google assistant> searchable apps & check your streaming apps are enabled or not.
Where do you live ? Could be related to that, just an idea.
Other than that, how is the picture quality?
