Hi, I fixed it with a temporary solution, changing the actions/global.php file of the amp plugin as follows.
if(isset($_GET[‘key’])) wp_redirect(add_query_arg(‘no-amp’, ‘1’, home_url( $wp->request ).’?’.http_build_query($_GET)));
else wp_redirect(add_query_arg(‘no-amp’, ‘1’, home_url( $wp->request )));
