gamma42 ,
I took a look at your site and saw your mobile only CSS code has the same width and height as the desktop version.

If you reduce the width and height of the mobile only CSS code, you should see it change. 😁
P.S. I noticed that your site also has a caching plugin, could you try clearing your cache?
