I wonder what the Mobile App versus Mobile Browser versus Desktop Browser usage percentages look like. Generally speaking, how important is it to actually update the desktop version other than for the sake of updating tech? I only use desktop as part of my marketing work, if I do it use it at all. (Side Note: I can't believe it took this long for Dark Mode to be a normal option for all software)
