Continuing the discussion from Redirecting an existing Desktop Site to the Webflow Smartphone view:
For everyone that’s also wondering about, this is a very hacky, but working way. Add this ONLY to your homepage, in the head.
<script type="text/javascript">
<!--
if (screen.width <= 520) {
window.location = "/url-here";
}
//-->
</script>
Note: you could also use “http://www.domain.com” as a url, but to stay dynamic, the forwardslash+pagename works better [and directly in the WF editor.
