I recommend replacing the default launcher. Google has packed so many fucking ads into their paid-for devices that it blows the mind to see. A good replacement launcher removes all that junk and the device runs faster too as a result. I did it on my nvidia shield pro (runs Android TV) and a google tv/chromecast I have too. Made the shield basically flawless and the best entertainment experience and the google tv it made much more useable.

The launcher I’ve been using is called “projectivy launcher” for the google tv. There’s a giant post over on XDA with specifics if interested. It’s made my google tv much better and I’d recommend the small asspain to try it. (I’m not affiliated with the launcher team or anything I just like it a lot)
