Started this morning on my iPhone. Previously, when I scroll down and reach the bottom of the page(in last reply mode)the next page will automatically load. In fact, I've posted here before about how the last topic or two is almost always repeated on the next page. Now the next page is not loading, though I'm having no other trouble with loading on other sites (Safari) or apps. I AM seeing a blank 'loading' bar at the bottom that seems to be new (at least I don't recall it before now).
This doesn't seem to be about some ad trying to load (as often causes a delay)but it could be that. Since I rarely use my laptop anymore, this is something I hope is not permanent.
