So, my "Lock Rotation" switch is grayed out. When I turn my SP3 into the portrait mode it switches to the tablet mode, but rotation still won't work. This bug was already reported in previous builds http://www.surfaceforums.net/threads/auto-rotation-bug-win-10.12227/ Any news on this? Or is it just me? I know I could try the registry, but why should I? It should just work, no?
