Hello,
We do not recommend you to change or modify the core files of the theme.
If you need to modify it you can always do it via a child theme.
Also we have inspected the site on mobile device, there is a link on the bottom that says
” View Full Site ” which then leads to the real site supposed to show on the device.
May be you have used a plugin or some custom coding to achieve this ? If so, you can remove the code or the plugin.
Hope it helps.
Regards.
