Only tested for H96 Max v58 (Rockchip RK3588).
If like me you don't like the new launcher you can install a new one. I've chosen the Leanback on Fire from @tsynik that is similar to the old Google Android TV Launcher (Leanback). It seems to work ok at the current time. I've used adb to install it
I have used Leanback on fire, others may work. APKs from the original Google Launcher didn't work.
adb install .\LeanbackOnFire_v1.55-release.apk
Go under settings and select the default launcher.
