I've noticed that my scroll interactions cause the mobile view to be zoomed out until the interaction loads. The interaction causing the issue is fading in from the right, so maybe that's causing the entire page to have a big white empty column on the right. Once the interaction loads, the empty space on the right disappears and the website fills the entire width of the page.
