So I saw the update yesterday, tried it, and it failed as above. But then I tried it again this morning and it worked fine. Not sure what has changed yet, other than when you swipe up and down in apps, instead of the screen pulling down or pushing above the bottom or top edge, you get a blue highlight at the top of bottom edge, and the screen does not move past the edges. Also, the screen lock seems to work consistently now, but I am not 100% sure yet.
