Question about Lenovo Active Pen 2

Hi
According to the manufacturer's website, it should be compatible...

I'm sorry, but the pen doesn't work on the X1 carbon (+ touch screen),
The pen doesn't work on the X1 carbon (+ touch screen). I have the impression that it only works on the Yoga.
Greetings

The active pen 2 works with the Lenovo C930 and C940. I guess it also works with the C340.
