When I turn on my laptop while it is connected to an external screen (my display settings are such that only the external screen is used while it is connected) and later disconnect it, Night Light does not work on the laptop screen (it did on the external screen). I have Night Light on "Manual Schedule" from 00:00 to 23:59 so it would always be on. Turning the Night Light setting off and on again does not help.
After restarting the laptop while it is not connected to the external screen, Night Light will work as expected.
