I don’t think this information belongs in the bug tracker, so I’m posting it here.
What happened
I was using my laptop at night, and when I was done, I put it to sleep (by closing the lid). The next time I opened it, I noticed that the Night Light transition took longer than I would have liked. When I checked the settings, I couldn't find an option to change the transition duration, because the "Swithing times" option was set to "Sunset and sunrise at manual location". I already knew that you can only change this setting when "Switching times" is set to "Custom times" option.This feels like a UI/UX issue to me. Imagine if someone experienced the same situation but didn’t know that transition duration can only be changed when “Switching times” is set to “Custom times”. I see frustration-inducing event here.
