Oh! my God!
I finally found that "Global Control Button" in main search window.
It cannot be seen when you play-back something.
It only shows their tiny appearance when nothing is played-back.
It located in the center and uppermost location of main search window when I really smoothly and very very cautiously hover the Oculus-Go controller.
As you said, I rebooted Oculus-Go, so, it was almost impossible to find the really small "Global Control Button".
It's size is so small comparing with other characters, so, most people cannot find if they reboot Oculus-Go.
Finding "Global Contro Button" is like a puzzle-Game.
And even after I changed the "Global Control Setting", I cannot make the button appear easily.
You have to be very patient to see the "Global Control Button".
I really shocked that how difficult they made to find this "Global Contro Button" .
Skybox has to fix this problem.
