Home Page Displays Text on Mobile

On a desktop the homepage at https://www.sharonbollum.com/ looks and works perfectly with the parallax effect.
On mobile, it goes to the default text that comes with the Shapely “Home Page” template. As a workaround, I’ve replaced the text with a static picture and that is what currently gets displayed on mobile devices.
How do I get mobile to display like the desktop page (at least the content - I’m not as concerned about the parallax effect.)
Thank you for your help!
