Ok. I was having the same problem with the apps not opening so I installed the Debug version on my iPhone. I added the Netflix app and the first window poped up and went away really fast. Not 100 percent sure what it said, but I think it said "Launching Custom App" then underneath "com.netflix.Netflix". The second window said "Checking File" then underneath "NO". The third window was the same as the first, but it didn't go away. It stayed on the screen for me to click ok. The few apps that worked just displayed the first window. Never shows the second or third.
Also, just a side note,
