Appium iOS can't inspect notification layer?

Vaadin 6 / 7 / 8

Hi,
Im utilizing
Appium
 to test my warnings in my iOS application. Im sending with another gadget a warning while the iOS application is in BG. At that point I swipe down utilizing :
((IOSDriver) wd).swipe(500,0,500,1000,1000);
The above works, the screen get looked down and I can physically observe the warning. The issue is that the appium still investigates the screen underneath. I checked appium overseer and it confirmed that it doesn’t perceive only the elemnts of the layer beneath the warnings one.

Any approach ??

Thanks
