How do I know brush pressure work with Cintig ?

I use Cintig 22HD touch and install driver after install Harmony 12.
I test many different brush pressure but not like in Harmony video tutorial.
In the video tutorial, a brush pressure is very nice.
How do I do?

Thank you.

go to Preferences and select Advanced, make sure Tablet Support is selected, it says to relaunch or turn off Harmony and reopened it, I had to restart my computer to make it work, I use a regular Pen and Tablet though
