Before there was a link in the comments section for mobile that allowed you to switch to the desktop version where you could post your comment or reply. I've noticed this was missing a while ago, but thought it was a temporary bug. I'm now more inclined to think it's a permanent change. Which is terrible, because the former link wasn't great, but it was way more intuitive than scrolling down past that enourmous, unrelated blocks of Fandom suggestion, to finally find a link to switch the page layout.
