Solved!
Hey Blip. I continued to dig and found this post, https://itch.io/t/442426/website-layout-forced-mobile-layout
He suggested placing this code into the CSS:
.right_col.column {
visibility: hidden;
height: 0px;
}
After an admin gave me access it was as simple as pasting that code into the Custom CSS field in the Theme Editor.
Poof, no more screenshots on mobile devices.
Hope that helps - John
