UIWebview - Apple Deprecated API usage. Apple store warning message UIWebview API deprecation

Hi All,

As mentioned here https://ionicframework.com/blog/understanding-itms-90809-uiwebview-api-deprecation, I have updated cordova-ios to 5.1.1 latest version and updated all my Cordova plugins. Still, I got the same warning message from the Apple side. Do you have any idea or I have missed anything to update or which plugin throws that deprecation message?
