When I put my Apple Watch on charge at night the always on display does not turn red
I have a series 9 Apple Watch and a few months ago I noticed that when I put my watch on charge at night the always on display does not turn red, it is always green. Did apple removed that feature or is there a problem with the sensor on my apple watch.
