Issue
AMP (Accelerated Mobile Pages) is a WordPress Plugin released to help improve mobile browsing experience. It is designed to render the page faster by loading the text and media only without scripts and many styles.
Since AMP renders the WP editor content in a minimal fashion, it is not fully compatible with Elementor created content.
Note
AMP does not necessarily improve SEO. Using AMP causes a page to load faster which may increase the number of visitors. This increase can improve SEO listing.
Solution
You can optimize your responsive website using Flexbox and other page speed improvement features of Elementor. For details about these speed improvements, see What Are Performance Experiments.
Important
If you experience the “Preview could not be loaded” error, it might be related to AMP. For more information, see Preview Could Not Be Loaded Error.
