I always had this problem…especially in the morning when there was 50+ threads with new posts.
I’m using iPhone Tapatalk 2.
In the old Tapatalk 1, it shows 98 Unread right now. Nothing in Participated. Upon scrolling down, it showed “Pull Up to Load More 50 of 98 loaded”.
Switching over to Tapatalk 2, it immediately showed Unread (99). When I scroll down, it automatically started loading more posts without the little message.
Looking at the web, I see a count of 100 in the Unread list. (posts are coming in).
Going back to Tapatalk 1, it now shows 99+ for Unread. It never would show more than 99+. And Tapatalk 2 now shows (103).
Maybe this is something that has just started working because this seems to be a lot more consistent than it was last night.
