Shopify Search & Discovery

Sorry to hear you're having trouble with your site. The Search & Discovery app customizes native features of Shopify's platform, for example, choosing your collection filters or product recommendations. It does not inject any custom elements or scripts into your website to display these though, that is required of the theme. So there wouldn't be a change in behaviour post-install. We recommend contacting your online store theme's developer for support to see if it's having issues working with native Shopify APIs and features. Alternatively, you could contact the developers of any recently installed apps to see if they run custom scripts on your site that may have caused this issue.
