It’s been confirmed to be a bug in Android though. There are articles saying Google is aware and the fix is coming in the next update.
But it’s only triggered if you manually toggle dark mode, then the schedule is disengaged. Then you have to manually turn the schedule off and on again, and it works. I just tried today and can confirm.
Don’t think this an OS issue per se. Both timed and sunset/sunrise work great on OneUI and Nova Launcher.

But it’s very annoying. I toggle it often.
