Hello, I have used a demo Surface in a store and it had haptic feedback (vibration) not only on the windows key but also on the on screen keyboard. After I bought one, before but also even after ALL updates, I still have not any haptic feedback on the on screen keyboard - just on the windows key. I have looked everywhere, I have made 3 times reset of every kind, but still not found anything. I even went back to the store just to be sure, and yes, it still has the haptic feedback to the on screen keyboard. Any ideas?
