When one of my FB-friends updates his status or posts a picture, I can see that it has maybe 1 "like". But if I tap on the friend's name, and view their timeline, I can see that the post in fact has, say, 23 "likes". How come that doesn't update in the news feed? Is it a known problem? Is there a quick fix? Yes, I have updated to the latest FB-app on my iPhone 4. Thanks!
