App Store white screen Flash Builder

Hello,

I'm developing a full flash app with Flash Builder 4.7 that is always rejected by the App Store review team.

In fact, when I develop with Flash Builder, I don't have any error from the console or the debugger.

But when I send the app to the App Store review team, at the second screen, they have a white screen, that can't allow them to use the app.

I have review my appon iPhone 4, iPhone 5, iPad 2, 3, Air, iPod Touch 4G, always with the latest version of the OS.

Could anybody tell me how can I see this bug, or review the app for sending it to them and finally validate the app ?

Thanks by advance

Regards

Mr Camacho
