Hello,
I just finished customizing the Casper theme and we noticed that if you try to scroll on mobile devices, the page gets “stuck” after the first scroll and only moves a very small amount and only starts behaving normally after the first swipe - this stuck behavior re-appears every now and then when you try to scroll again after reading some text.
This is the aforementioned site: https://magazin.getcaya.com/
I am testing on a Pixel 2 XL but this issue reportedly also appears on iPhones

Thanks!
