I have my Wacom setup to scroll using two-finger press but Photo AI overrides it and instead zooms in/out. Huh? The expected shortcut for zooming in pinching with thumb and forefinger. That works, so I have two methods for zooming, but have to hold down Space and then stylus to scroll, when I could simply use two-finger press and scroll. Please follow other apps that all use pinch to zoom, and two-fingers to scroll (customisable, so not all may use two-fingers but all apps I use, such as Photoshop, ACR, Lightroom, honour my Wacom prefs).
