2) Are you talking about free shipping message in the mini-cart? You can change that in Theme Options > Header builder > Cart > edit mini-cart content. Or provide us with the screenshot for better understanding if you are talking about another thing.
3) Do you use third-party plugin for the tracking? Does this plugin send email? Contact plugin author to get help with this then. Because our theme does not have tracking emails by default.
Because AMP uses minimal code for quick loading, it can’t include all the elements on a fully functioning webpage, such as certain widgets, embedded content, or pages created using page builders (Elementor/WPBakery).
5) Do you use any multivendor plugin? Contact multivendor plugin author to get help with this question because it’s related to plugin settings, not to theme settings. We are able to help you with theme settings only.
6) Our theme does not have any membership form. Could you, please, explain me what form you are talking about? Provide us with screenshot or link to the form for better understanding.
