We keep encountering this issue. When you hold the Oculus botton to fix the location of the menu, it keeps freezing on us.Once it unfreezes it is not fixed. Have tried restarting multiple times and it is still freezing.
This started happening to me a few days ago with the new firmware. A hard reset resolves the problem and it doesn't reappear in the same session but then when I pick the headset up the next day it happens again. Very annoying.
