I can't get the 'choose default launcher' dialog to come up unless I disable the Google TV launcher and Setup Assistant with adb first, and disabling those breaks Assistant voice commands as well as the notifications sidebar. What is the correct way to change the launcher on this TV?
Download Android TV version of Launcher Manager here https://forum.xda-developers.com/t/app-firetv-noroot-launcher-manager-change-launcher-without-root.4176349/ Install other launcher you want to use, open launcher manager and change your launcher there.
