auto light/dark mode not working (sunset to sunrise)

Recently i noticed that dark mode (not night shift) didn’t turn on even after 2 hours after sunset. I decided to turn off and on again the “Automatic” switch (Settings > Display & Brightness) and then dark mode finally turned on. It worked as it should previously, but for some reason it stopped working now.

“automatic” options are set to “sunset to sunrise”, not “custom schedule”

Updated iOS 15.3 to 15.5

All system location services, including “setting time zone” and “system customisation” are on

Time zone is set to auto
