There’s not “undo” from whiteboard, there’s just “normal undo” in the gestures
For now, I don’t think of useful use cases of the “whiteboard undo” gesture.
While whiteboard is enabled and shown, gestures don’t work. Tap just draws a dot, and swipe just draws a line. That is, the “whiteboard undo” gesture can’t be used when the drawing to be undone is shown.
(It might make some sense with keyboard or joystick controls, though.)
Yeah, I notice that. I (or we) would use one of the volume buttons
