Directional light and sun

Hi. yesterday i deleted directional light (named Light Source) in my FPS project, i tried add new to see how looks blank dir. light, but i forgot do steps back and i saved it. Now is my sun sticked in one position on the sky and rotating new directional light has no affect to sun in skyBP i tried rename DL how it was before, builded lights or whole project, but nothing works and then i created new fps project but here is same thing… i can’t change sun position while rotating dir. light.
Please help somebody.

Are you using a sky sphere?
If you are using a sky sphere, there is an update material expression in the the details tab.
also the light has to be declared as its controlling directional light.
