Well.. Manually you can choose dark theme from Google's Chrome App by going to settings and then Theme and finally one out of three options available..And it is there... And presently I have not received any update, it was updated Earlier...But Once you Enable Dark theme on your System (Phone) it is to be Automatically applied to all and if not possible for all then at least most of these Apps...Like presently if you enable Dark Theme on system it will automatically implemented on Samsung Internet app, Google Play Store etc..Managing from every frequent using Apps individually or Manually is bit unjustified...All apps should get updated in such a way that once Dark theme applied on System it is to be applied Everywhere Automatically and if Manually in individual settings then one should have a Customised Time setting (Like from 7Pm-6.30Am)..And my present comment on Google Chrome is till my last update & I haven't received any update till 9.44Am today..
