Hello Jaun,
Thank you so much for using our theme SuperMagPro. In case of Ad Sense responsive on mobile, you need to reload the site once again on mobile and then it will be responsive, otherwise it will not responsive at all. So, try once by viewing from the mobile device and if the header advertisement is not responsive, please reload the page. This is not the fault on the theme, it’s all about Ad sense problem. Hope you will understand.
Warm Regards,
Acme Supports
