As I was about to ship an update Monday, I remembered this link. The app in question is an older app, built when having a free and paid version was the way to go. The paid version still sells, so I keep it going. However, the free version has the word 'free' in the title and app icon. Based on recent news, rather than risking a rejection, I removed the word in both and the app was approved on first submission. It pays to pay attention to the news!
