Adaptive brightness not working

Adabtive brightness is not working and I don't know how to adjust it.

Try settings and then display, the slider to adjust the brightness is there along with the option to turn the adaptive brightness on or off.

Yeah, I did that, even if the the adaptive brightness is on it does not automatically increase or decrease the brightness as it used to do before.

You can use the slider to manually set the brightness to the level you want if the adaptive brightness isn't doing it for you.
