Widgets containing Iframes not working on IOS

Hi All, I’m in the process of creating some new widgets I was missing myself for my wall mounted dashboard. For this I will be using some iframes too, for example YouTube and Windy. All of this is working fine on android and displays nicely and I was looking into publishing the widgets for others to use too.

The only thing is when using the same widgets on a IOS device they are not loading the iframe. My guess it has something todo with the security settings of homey or there implementation of the wkwebviewconfiguration item. When I use the debugging options I do not see any errors just a white screen.

Is there someone who knows more about this and can help me? I will place a simple widget example below:

// index.html

<html>
  <head>
    <style>
      /* Example of a custom CSS class. */
      .custom-image-class {
        margin: var(--homey-su-3) auto var(--homey-su-5);
      }
    </style>
  </head>

  <body class="homey-widget">
    <iframe width="650" height="450" src="https://embed.windy.com/embed.html?type=map&location=coordinates&metricRain=default&metricTemp=default&metricWind=default&zoom=5&overlay=wind&product=ecmwf&level=surface&lat=52.215&lon=6.015" frameborder="0"></iframe>
    <script type="text/javascript">
      function onHomeyReady(Homey) {
        Homey.ready();

        // View the settings the user provided if your widget has settings.
        console.log('Widget settings:', Homey.getSettings());

        // Fetch something from your app.
        Homey.api('GET', '/', {})
          .then((result) => {
            console.log(result);
          })
          .catch(console.error);
      }
    </script>
  </body>
</html>

Some more information on what I see in the debugger. In the network tab there is not even going out a fetch request from the Iframe giving me the impression this really could be a setting that needs to be enabled for the IOS app.
