## What it means

A script an app adds to your storefront does not load, and Rabbot cannot tell what that app does on the page. Whatever the app shows or runs for shoppers there may be missing.

## What to do

Usually an app that was removed or updated while its embed stayed switched on. Open Online Store > Themes > Customize > App embeds and check the apps listed there. Rabbot checks again on its next scheduled check and closes this once the file loads.
