Showing white screen in webview on app getting foreground from background

Hi,

Scenario: webview showing blank white screen on getting back from background to foreground.
I am getting the white background with scroll. It seems page content is there but showing me blank white. Some time its back and show but many time got stuck with the blank white screen. We have no option to reload or restart the app.
The app is blocked to live on store due to this.

Could anybody help me.
