Ahhh I think this explains a lot. I actually routinely, instinctively look for that link on most sites, because it does happen quite a lot. There's a bit of an odd issue with the desktop skin, where I suspect on some window sizes/browsers/systems, the link to switch to desktop appears or disappears. For my usual scaling and browser (on desktop), a link only appears if i resize the window so it's narrow, and then I see "View Desktop Site" show up in the hamburger menu.

I also see a "view full site" button in the skin source somewhere, but I didn't immediately figure out how to get it to show up and didn't find it on the page with ctrl+f, but maybe I missed something else.
