If I’m tracking replies in a thread then it shows me how many new posts have been made since my last view. For the past week or so, this isn’t working. It will show that there are 10 new posts so I click on the thread to catch up only to find I’ve already read it. I’ve even liked some of the posts.
It’s not a big deal, but I’ve been spoiled by the site keeping track of what I’ve viewed. It’s nice being able to pick up where I left off instead of rereading posts.
