Night light isn't automatically toggling on / off

I don’t know if this is only Gigaset issue but night light won’t toggle on / off automatically. No difference if I turn on GPS or not (some night light programs depend on GPS being toggled on)
I’m having it set to “toggle on from sunset to sunrise”.

Turn the night mode completely off again and then on again.
I also had this problem with LineageOS on my Oneplus 5.
