The app can not work several weeks ago. I also tried to find new method to see the pending friends list, but I failed. Got the answer on "Help Center" of Facebook: How do I view friend requests I've sent that are still pending? Can I see which requests haven't yet been accepted? There's currently no place on the site where you can see all your sent pending requests. However, if you go to someone's profile (timeline) you can tell your friend status based on the following. If you see Add as Friend, then you don't have a friend request pending. If you see Awaiting friend confirmation, you'll know that you've sent a request that hasn't yet been confirmed. If you see the Remove friend link, you'll know you've both confirmed your friendship.
