When I have my Adobe Ink stylus connected, it enables palm rejection and disables the two finger pan and zoom gestures. Despite this, the two finger gestures for undo/redo remain enabled, with no option to disable them. This makes it difficult, if not impossible to use a connected stylus in palm rejection mode, as the motion of one's hand on the screen will inadvertently trigger undo/redo actions while drawing. This is a glaring oversight in the design of the app's UI, and one that I hope will be corrected. Thanks!
I just responded by email to your in-app feedback.
