It seems to me and from what I’ve been hearing and reading that everything is a server side switch. Having said that I can say some of us including me used to have a dark mode play store app and now don’t, switch turned off again.? Hard to say.
I also notice several apps I use are dark mode but only if I force dark thru dev settings. So it seemed they are not fully baked yet either because we shouldn’t need to “force dark” to make it work. Little by little and bit by bit it is coming, just need to forget about it and be pleasantly surprised when it shows up.
I hear that iOS will have a dark gmail also and it is supposed to be released soon. Since I also have an iPhone, I have been watching for it. I wonder who will be first?
Really happy to see a dark assistant now since it used to light up an entire room annoyingly when I would ask something before sunup.
