My wife and I really like using 3D Touch for moving the cursor around (i.e. turning the keyboard into a trackpad when typing etc). It works MOST of the time. But there are occasions where no matter how hard we press on the keyboard (she has the 6s, and I have the 6s Plus), it refuses to turn into trackpad mode. Very annoying. I was hoping this would be addressed in 9.1, but it doesn't seem to have been. Anyone have thoughts on this?
