I checked to see if the settings in Artstudio for pencil only mode finger undo was enabled. It was. I also checked to see if two or three finger undo was enabled. It was also enabled as well. However, after doing a series of random scribbles I tested to see if undo would undo all the scribbles. It undid most of the scribbles on the canvas...but not all of them. In fact it failed to undo all the scribbles. I had to manually erase the remaining scribbles. I’d classify this as a bug. I’d like to see this confirmed.
