wp forms or option to email

Hi! First, I’d like to say thank you for creating this plugin. ?? You’ve saved me quite a bit of work!! But I’m wondering if you can help me with something.

Wondering why the shortcode for WP Forms insn’t working in this puzzle when it’s completed. If it’s not compatible, is there a way to add some kind of notification to show the site owners who has completed the puzzle via email?

Also, it would be nice to include a screenshot of the completed puzzle in the notification. ??
