Make sure your Wacom Cintiq and CC 2919 are both using Microsoft INK API. I have CS3 and CS6 installed as well as CC 2014, CC 2018 and CC 2019. CS3 and CS6 only have Wintab API support so I configure my Wacom to use WinTab not to use Microsoft INK Api with Photoshop and configure Photoshop CC version not to use Microsoft INK api. Pen presure works ins all version of Photoshop on my machine.
