Dear community,

I am in the process of creating a site for a podcast about childrens books and I am having a small problem with the mobile variant.
Basically everything looks fine but when instead of having the menu appear the phone zooms in on the hamburger menu bar.
This is not an ideal experience for the user, but I don't know how to fix it. Any ideas.

Here is the site. Please view it on mobile to help me so you could see the problem. http://childrensbookradio.com

Thanks Again :-)
