amp plugin set up

during set up, my site won’t scan. It says site scan failed try again. Also, when activated, my shortcodes (amazon created in Gutenberg) stop working. The links disappear in the published post. Please help. I really want to use this plugin. I have astra theme and set the mode to transitional (as suggested by other web research). This plugin is supposed to be compatible with my theme but I continue to have problems. Thank you.
