cordovaInAppBrowser and ios9 not working

I have simple project of cordova & webview.
Webview was working fine one year ago with <= ios 8 opening the links in the app that had _blank and other domain url in a new external browser window.
Now with the ios9, the whole webview stopped working because of strict https requirements.
Opening the webview I got working with NSAppTransrportSecurty-setting in xcode, but now none of the site-external links will open anymore. Nothing happens when clicking.
And there is no way to make the links in the website to open in the external browser either, internal or external. Not with window.open or with _blank parameter.

How to make links open from webview-site into external browser window in >ios 9 ?
