Sonar Theme: Scroll Issue

I am having scrolling bugs on the Sonar Theme. It glitches on mobile when you try to scroll up/down the home page and then carousel buttons are not selectable. Is there a way to disable the custom scrolling? Does this have to do with the div wow for the images?

Hey there

Issue is within the index.html.
After some research, it seems to be an Android mobile issue. It works fine on iOS and both mac and pc. Only glitches on Android native browser (google chrome mobile). The header works on mobile, but once you get to the “portfolio” section of index.html, the scroll glitch starts and user is not able to scroll properly because it will stutter up and down constantly.
