I noticed that a lot of the latest threads displayed, circa 20 in the last hour, dissapeared when I logged in, see the two screenshots below, before and after login;
In 'Notifications' there are no blocked or muted users.
In the Notifications\Categories, there are none shown as blocked. I found 'Programming Questions' in the list, I have not been shown posts in this section, selected it and it went the the top of the list but with a black cross against it, so presumably that means blocked.
The affect of the problem, is that I only see about 1 in 5 posts in the 'Latest' view.
Programming Questions is one that is being blocked, but my profile appears to say its not blocked.
I see the similar behaviour of the forum, but not consider it as "issue". There are some settings that can cause this behaviour - for example, for registered user post are treated as new only one or two days and than than it will be hidden from view.
Again, I don't see this as a problem.
I have seen more than 200 posts in "Latest" in that category (in fact, much more, because when scrolling to the end, the list automatically lengthens).
But in my "Latest" view all messages are shown, and not just for 24 hours
