FWIF I had installed this on my TS4K but reverted back. Though you can get the GUI working pretty well, there is not a way to update your watchlist preferences or have it to only check apps you have installed.
If you click the customize preferences button at the bottom it just crashes and relaunches the Home Screen. I couldn’t find out which additional APK or package may be needed so I just went back to the regular Android TV screen.
All those who say it’s working 100% are mistaken. There are caveats.
I managed to solved it. Here's how
Did you also install the latest Google Base APK?
If it’s anything similar to the problem I’m facing with plex this might be due to the fact that it looses the internet connection while booting. Try force quitting the app and make sure that internet is connected. A 2.4GHz connection with a static IP should help since it’s more stable than 5GHz. Alternatively an Ethernet cable should do the job. I might be completely wrong on this though lol
What is Google Home TV?
