This never worked perfectly. It was difficult in past games to find a time of a day that correctly displayed sunset, but in FIFA 19 absolutely all evening times will only display total dark night time or daylight just like midday!
I'm playing on Xbox One X. Don't know about other consoles/devices.
Tried all seasons and all sunset times available. Absolutely no single one works.
At least in career mode sunset times still work. But I'm really afraid it disappear also from there.
