Issue with scrollContainer

Hi fellas,

hope you are doing great. I made this little website: https://rdcl.it/

It’s basically two websites in one: on desktop it has a small “browser” like container in which the scrolling is happening. I have used:

var wow = new WOW({
offset: 0,
scrollContainer: ".navigatr .chrome.middle"
});			
wow.init();

But on mobile it does not scroll anymore, except for the portions that are in the viewport when loading.

Can any of you help me figure out what the issue may be, please?
