On the localhost module, lazy loading is working fine, showing meta tags and HTML content in <app-root><app-root/> in the view page source, but it is not showing on the live server. On the live server, I can only see meta tags and HTML contents of components that are direct children of AppModule but lazy loaded modules components are not showing meta tags and HTML. This weird behavior is only on the live server.
