In doing a search I found similar requests. Seem like everything should be working in the latest.
I am not using WKWebview, I couldn’t not get the Cors stuff working. (Worked for the first request but not the second).
Iphone 7 with ios 10
I darkened the border so the space would be noticable.
In debugging the code
<ion-nave bar class="toolbar toolbar-ios statusbar-padding"> has padding-top:cal(20px +4px);
If I took that out it would look fine.
This is only on pre iOS 11 iphones.
On the Iphone 8 with ios 11 things look fine.
I know there was some other plugin for ios11 status bar. Wasn’t sure if that would fix this problem.
