Canvas size it measures in millimeters

Canvas Size : Every time I reopen it, it measures in millimeters. I have to switch it back to centimeters each time. It used to stay where it was last displayed. And the arrows showing which direction the page should open are gone too. What kind of innovation is this? Although it's worse than before, I understand your desire for visual changes, but you're wasting my time by making me change the unit of measurement every time.
