I have tried to change hook numbers, but it doesn’t help, it moves the button, but it still stays in the middle between variations and plugin..
remove_action( 'woocommerce_single_product_summary', 'woocommerce_template_single_add_to_cart', 30 );
add_action( 'woocommerce_single_product_summary', 'woocommerce_template_single_add_to_cart', 70 );
