Hello,
1) Provide us with WP Dashboard access to your site to check the issue in more detail.
2)
I read in their documentation that it is compatible with the elementor,
What is compatible with Elementor? WooCommerce? In what documentation? Provide us with link for better understanding.
XStore AMP (Accelerated Mobile Pages) is a plugin released to help improve the mobile browsing experience. It is created to render the page faster by only loading the text, media, simple styles without scripts and many styles that Elementor plugin generates, so it supports the WooCommerce page (because they are simple pages) and does not support pages created Elementor.
Regards
