Where did you share the info? as I can't see it in this topic.
For the issue, try to open the file: templates/no1_shopping/vertex/includes/vertex_includes_header.php
Look for this line of code:
<meta name=“viewport” content=“initial-scale=1.0" />
change it to:
<meta name=“viewport” content=“width=device-width, initial-scale=1, maximum-scale=1, user-scalable=yes”/>
clear cache and see how it goes.
