Why isn't my mobile site menu functioning properly?

[hausbyhaleigh]

Hi there! I have an issue with the online store that I built using the Brooklyn theme. The menu isn’t working on mobile devices when I initially open up the site. After clicking on the menu icon at the upper left corner when first loading the site- nothing opens. If I am on any other page besides the home page, it will open. I can't figure this out! The solutions I have found online did not work for my store. 

Also - I would love to change the heading font to Tan Pearl. I have already uploaded all the necessary assets (the font files in various formats) but I can't figure out where to change the code! I will eventually want to change the font of the body/header text as well so that all font on my site is cohesive with my logo. 

My online store link is: hausbyhaleigh.com

Thanks so much in advance.

Hi thank you,

to do this do I just delete all code that mentions jquery?
