My games works perfectly on my devices (iPad Air and iPhone 5), but they are rejected from app store. I got the next message
“2.2 Details
We discovered one or more bugs in your app when reviewed on iPad running iOS 8.4 and iPhone running iOS 8.4 on both Wi-Fi and cellular networks.
Specifically, the app displays a blank black screen shortly after launch.”
and the screenshot

How we can see there is black screen and advert.
I can’t understand what is wrong with my app because on y devices everything works.

Any errors written out by the game as it starts up on a device? Are your test devices using iOS8.4?
