Yesterday evening while doing a Google search, I was presented with an option to try a 'dark mode beta' on the Google App on my phone ( iPhone 8 plus, iOS12.4) I clicked on it and followed very simple instruction to go to settings & select it. It is, like any dark option, a delight to use and much easier on the eyes. I cannot however do the same on my iPad mini 4 yet ( also iOS 12.4) as it hasn't updated ( Both iPhone & iPad show Aug 27 & 28 for Google app last update) Has anyone seen the 'dark beta' prompt in the Google App yet, particularly on iPad? I'll do iOS 13 when it comes out for public download, with the caveat that I will likely hold off to digest feedback for the first few weeks, and get to it at about iOS 13.0.1 or 13.0.2 just to let early glitches shake themselves out. That habit has served me well for major ( yearly) updates so far...
