Buttons not working on mobile using React

Question

I deployed a dummy gatsby project on gatsby.io and it works fine on my laptop but when i view it from my phone, none of the buttons seem to be working. It also doesn't seem to recognise scroll events, almost like there's no functionality in the site.

Note: The site works perfectly fine on my laptop

Here's the link to the dummy site https://drivingwebsite.gatsbyjs.io/
