How to disable the mobile view?

Hi there,
I have been using Moesia theme to build my site. It looks great on my laptop’s screen but looks terrible on mobile devices.Everything is squashed making the site unbearably long to read (and there isn’t even that much text there…) It is crucial for my site to retain the same look on mobile device as I created for desktop computers and laptops. I was hoping to complete and launch the site by now but it really doesn’t look good enough to do that yet. Is there any way to disable the mobile view? I tried in Page Builder by disabling responsive layout and changing the width of the device screen but this doesn’t seem to have any impact on the site whatsoever.Please, please help.
Kind regards,
