Footer Content not displaying on all devices

I am using the Footer Content plugin on multisite primarily for the purpose of our Pro Site subscribers affiliate banner.

The banner is not always displaying. The following example for site https://essentialoilswithlark.usingessentialoils.com/
When I view the site using Windows Chrome, the banner is displaying, however, when our Pro Site subscriber views her site also using Windows Chrome, the footer content is not being displayed. I've attached screenshots of the 2 variations. Please help with this display issue.
