USING ADOBE AUDITION CC2020 WTH PRESONUS FADER PORTV 2

Hi - not sure if anyone can help with this. I can't find anything very comprehensive online. I am trying to use a Presonus FaderPort 2 with Adobe Audition as a control surface. I have follwed Adobe's instructions on how to seelect this control surfae in the menu but the only control that works on the Fader Port is the motorised fader. I can't get any transport control or any other button functionality. I have contacted Adobe who suggested I contact Presonus and thet suggested it was a Adobe issue. Adobe suggest that it is possible to get full control but I'm stuck in the middle! Is there anyone out there sucessfilly using a FP2 with Audition CC 2020? Help much appreciated.
