Hi @hollam,
Thanks for contacting us; I have checked your website that is using AMP with the oceanWP; in their documentation they mention what are the best templates to use with AMP.
But oceanWP and Gutenberg are AMP-compatible, but in your case, you are using Elementor, and unfortunately, Elementor is not fully AMP compatible. As a result, you may encounter some validation errors and some Elementor features which may not render as expected in their AMP versions due to AMP’s removal of Elementor’s custom JavaScript. You can follow this GitHub issue for future updates on Elementor compatibility.
You can also try using the AMP Enhancer plugin, which adds a layer of AMP compatibility for Elementor and several other plugins.
