Why are the interfaces for the mobile sites so different?

I would like to use them in the same way on each site. In my humble opinion, the interface on stackoverflow.com is the most appropriate.

(I use Android 10 + Chrome)

    Looks like you're using the "mobile site", not the "full" or "responsive" site on the lower image. Scroll to the bottom and touch "Full Site".

  • Thanks. For all interested: Options is on the bottom of page and is called "full site". ah.. I see you edit your post in time when I found this (thanks to you) and describe. Commented Jan 31, 2021 at 23:40
  • By the way, I haven't changed anything myself before and this begs my question: Shouldn't all pages have the same initial settings? Commented Jan 31, 2021 at 23:46

    Each site has it own set of cookies; changing the site mode on one site won't affect the other. They aren't a setting you change in your preferences, so it's not saved to your profile.

  • This is not what I was asking for. I know how cookies work. I thought about if I do not change anything at the first time I start using each page, Why they have different initial setting ? ... Or I miss something - maybe I just do not focus when I change them. Commented Jan 31, 2021 at 23:48

    Super User and Stack Overflow are different sites. It doesn't matter that you've changed your site mode on Stack Overflow, if you haven't on Super User it'll use the "mobile" version of the site. Clearly you changed the mode on Stack Overflow but not on Super User and why they look different. Changing it on one doesn't change it for all of them. If you haven't selected the other mode, they'll default the the "mobile" version on a mobile device.

    The responsive design you see in StackOverflow is fairly new, but not everything optimized for mobile yet. I believe there are plans to eventually retire the mobile theme (the one you can see in the bottom screenshot). At that point, the responsive theme will become default. Commented Feb 2, 2021 at 6:54

    StackOverflow also defaults to the mobile theme, but you probably switched to the full site at some point in the past. Commented Feb 2, 2021 at 6:55
  • Today all my followed sites switched again. Commented Mar 19, 2021 at 16:26
