Why is my mobile site not scrolling properly?

the mobile version of the shop is a little funky, at least on my phone and my friends. It doesn't scroll properly all the way and like jumps between pages.

 here is my website  https://sudibear.com/

It works fine when I use the phone view on pc to edit . however my issue is that when you try to browse my website on phone its jumpy and scroll doesn't work properly
