WF: _Webfilterisactive returning: NO

Question

I have a problem in the following scenario:

I am consuming data from a Json API, I am inserting this data into an html file that is in my project to be displayed in a webview.

When I open webview the message below appears in the Xcode console and the content I injected into html is not rendered. If I insert any content into the html it appears on the screen, but what I injected into the html using javascript does not render.

the problem only happens on IOS, on android is working perfectly.

    filterBlacklist =     (
    );
    filterWhitelist =     (
    );
    restrictWeb = 1;
    useContentFilter = 0;
    useContentFilterOverrides = 0;
    whitelistEnabled = 0;
}

Thank you very much!
