Photoshop 2021 not working for WACOM Intuos

Hello,

I try to map functions of my WACOM tablet for Photoshop 2021. I open Wacom Tablet Preferences, Device is Intuos Pro M, Tool is Pro Pen 2 and I added Application 'Adobe Photoshop 2021' (it was in the proposed list). I map the upper buttom of the pen to act as a 'right click' and close the Preferences. However, in photoshop, it doesn't work. Photoshop takes all the settings from 'All Other' Application. In Lightroom, it works OK. Mapping an 'ExpressKey' for Application 'Adobe Photoshop 2021' doesn't work either. The only way to use the tablet in Photoshop 2021 is to alter the settings for Application 'All Other' (which I don't want to do). Any help ? (PS: it is on a MacBook Pro).
