On mobile when pressing on a thread that has new posts, it seems like it doesn't always take me to the new posts, sometimes going to the original post on the first page instead. I tried twice in a row on one thread (in the Switch forum fwiw), first time I went to the original post, then I went back, and second time I went to the new posts.
Not just for that reason, but also in general, please could the "Jump to new" button that exists on the desktop site also be added to the mobile site? There looks to be space for it in the same kind of area to the right of the page numbers. Some links in certain parts of the site (eg. the front page headline links iirc) always take you to the start of the thread rather than the new posts anyway, so it would be really useful to have.
