Facebook App Wall Posting no longer showing in Facebook iPhone App

I use the GRAPH API with django for Facebook wall postings. Since yesterday, the wall posts only show on the Facebook web app but not the Facebook iPhone app. I tried Yelp, and their postings still show开发者_Go百科 up. How can I debug this? Anyone notice this issue with their Facebook connect? Is this a Facebook algorithm issue.

Code for Wall Post:

graph = facebook.GraphAPI(access_token)
        attachment = {"name": name,
             "link": link,
             #"caption": "{*actor*} posted a new review",
             "description": desc,
             "picture": picture }
        graph.put_wall_post("",attachment)

I have the same problem. I am writing an iPhone app in Objective C and my post code uses the FBStreamDialog box to prompt for input and then post to a news feed. So, it appears the problem is more likely to be a Facebook problem rather than a coding problem.
