FYI: on my remote I think the three line button might have been replaced with the word "menu"
and to find the version number I have to go to settings/more/apps/system apps/buzz tv2/and a screen pops up with option to force stop/uninstall and that is where a icon with buzz tv2 has the version number. Also the clear cache, data, and uninstall options.
If I right click or left click the buzz app in the home menu/apps it starts live tv
