Page Scrolls Under iOS system header (showing clock, etc.)

Hi team,

I’m trying to fix the issue shown, where the bubble page scrolls under the top of the iPhone header area. I need it to stop showing at the top of the floating icon toolbar. At the same time I need that uppermost background to be black, not white so it’s visible the iOS widgets are visible before the scroll starts.

Scroll Under Issue

Thanks in advance for your help! Much appreciated!
