"Send Plain Text Emails" plugin doesn't work with WooCommerce and MailPoet as advertised
Hello, I just purchased and installed the "Send Plain Text Emails" email developed by Affiliate Web Designers (https://www.affiliatewebdesigners.com/shop/send-plain-text-emails-wordpress-plugin/?attribute_pa_license=single-site-license). Their support page states "Our AWD Support page is closed, but you can still find and talk to Dave Hilditch and his team over at www.superspeedyplugins.com," which is why I'm contacting you here.
The product page I shared advertises that the plugin should add a button to WooCommerce's orders page and MailPoet's subscribers page. I have up-to-date versions of each of these plugins. I've looked very closely, and no button is appearing. Is there a solution for this? If not, I would like to request a refund.
