Thanks, I started working on adding support for it. I got it to properly display the captcha and check it upon form submission. The UI doesn’t indicate nicely if you failed to pass the turnstile. I’ll send a pull request once I get it more polished.
btw I think there is a bug in inc/turnstille.php. The function cfturnstile_disable_button_styles is intended to be called with $button_id, but the action parameter is actually $unique_id.
