White Screen after loading (iphone 7)

Hello guys.

After the panel loading, the content becomes blank (but only hidden, it can still be clicked).

This error happens only on the iPhone 7. In iphone 5s works perfectly. On android also works.

The plugin used in the panel is chart.js 2.6.0.

And the plugin is being used: cordova-plugin-ionic-webview: “^ 1.1.16”

Anyone have any idea what it can be ??
