I finally upgraded to Oreo on my shield. I don't love it but I will get used to it. One complaint though is that the game row is now the GeForce gaming platform rather than the game row from the previous OS.
I liked having shortcut to my own games and more control on there. Hope Nvidia or Google gives the option to customize the game row more.
You might want to consider using ADB to replace the Leanback Launcher with a better launcher that you can configure to your liking including adding a dedicated row for your games. Right now I am using the HAL Launcher.
I thought there was a my games channel?
Regardless, why are you posting this here? Its reddit. Not nvidias forums. Go to the actual nvidia shield forums.
Yep. I got a Shield just a few days ago and not having a dedicated game favourites row is frustrating.
