Wow- finally I see I'm not the ony one. Took me hours today to figure this out.
I have a brand new HP Envy (just a few days ago), and installed Win10pro, MS Office Pro and had the ink workspace. Looks good to me, so I ordered the HP Tilt Pen - ready for the future.
Hell no! I received the tilt pen today, and the ink-space was not showing up anymore.
Thought is had to do with drivers for this pen/stylus. but it's not.
So I spend a lot of money (almost EUR 2000), now leaving me with a tilt pen that doesn't support the tilt option anymore. Just after a few hours I received it.
Called the HP support and they told me that the tilt option is only available in Sketchpad and not whiteboard.....
Glad to see it has nothing to do with the hardware itself, just stupid sw engineers.
As-we-speak I am busy rolling back updates, and kill the updates voor next few months. Hope MSoft will give a good alternative in the mean time.
