I just realized that on my Facebook profile, my ‘Recent Posts’ for the WordPress application are showing back to September 04/07. The automatic displaying of new posts as they get published isn’t working. You can go into the options within the WordPress application and select the number of posts, and that should make the most recent posts show up on the Facebook app. Looking at the most recent wall and thread posts for the WordPress app it looks like a few users are having the same problem, and some are unable to get a refresh of posts, even after manually refreshing. I wasn’t paying attention to my recent posts to notice this until tonight, but it looks like some users were having these issues back as far as August.
This post showed immediately on Facebook, after having done the manual refresh.
