MailPoet2, unsubscribe undo not working

Hi, I have just created a child theme because I noticed the unsubscribe-undo did not work. I have probably lost a number of subscribers who thought they had been able to undo their subscription which turned out not to work. I have found the page explaining how to customize the ‘sorry to see you go’-page and I followed your instructions to the letter. I have copied-pasted the code onto the bottom of the functions.php file and added the shortcode into the page using the shortcode block of WordPress.
The shortcode does not appear as a shortcode but as an ordinary text and it does not link to anything. I am at a loss what to do next, as it is important I get this working correctly. Thanks for any help you can offer.
