Hi there
I am getting Problems with the responsiveness on Windows Phone 10. Maybe there is someone who already had the same issue and solved it. I have a simply responsive html newsletter (with media queries) which does not work on Windows Mobile Phone 10. I already tried specifics hacks but nothing had worked:

<meta http-equiv="X-UA-Compatible" content="IE-edge">

<style type="text/css">
    @media only screen and (max-width:480px) {
        @-ms-viewport { width:320px; }
        @viewport { width:320px; }

The older Window Phone Version 8 works well.

Here picture how it looks on Windows Phone 10:

And how it should look:

Does anyone has another solution?

Thanks for any Help!
