If you can see Product Fruits with our Chrome extension loaded but it won't load without the extension, it heads to the integration problem.
You can check if the Product Fruits is installed by using DevTools. Open the browser console and type productFruits. When you press Enter and see something like Uncaught ReferenceError: productFruits is not defined or undefined, it means Product Fruits is not installed properly. Your developers must check and fix this.
