I recently upgraded to Pro 23 mainly for the AI smart masking, but I am disappointed.

It does work but needs a lot of manual adjustments.

My main concern was that I could not change the tool bar option (+ mask, - mask, box selection) so impossible to edit the mask.

I have since discovered if I resize the video to its original size by double clicking the mouse wheel over the video display (No zoom) I can then select the tool and re zoom to edit.

I hope this helps anyone with the same issue as when I searched for help I found nothing.
