does anyone know why Google doesn't have Dark mode in the android ONE project ?

They had activated it for some time. After that, they again went back to blinding white colour.

But for me it never works.... I thought they were having issues hence they reverted back to All White view.

Care to share screenshot with dark mode for Google app?

I think dark mode for google was not available for all stock and android one devices for few times due to some server glitch which google resolved in last week and now it is available to all.
