When I launch my app, it stucks in the iPhone apps screen for 4,5 seconds
<p>My app is an enterprise app.
When I click on the app icon, the icon is dimmed, and stucks for 4-5 seconds.( It depends, some users report it stuck for 10 seconds.)</p>

<p>I connect the device to look into the console.
I found some exception is through. But no idea if it is related and what it really did. Any idea?
