I always use the mobile site. In the past after I've read a post and click back ( i read the active posts ) it would take me back to where I was and would just scroll on from there.
Now once I come out of a thread its taken me back to the top of the list of threads. New ones have appeared and sometimes the one I have just read has vanished ( its not been deleted cause it shows up later ) its like the page has refreshed while I've been reading one thread.
Why is this? Very annoying
