Error since last update, conflicting with WooCommerce Waitlist

Hi

Since the last update to 1.0.1.3 (I am not sure which version I was on before) I am not able to send e-mails from the (official) WooCommerce Waitlist plug-in, in the debug log it shows error from your plug-in:

[28-Feb-2021 04:38:52 UTC] PHP Fatal error:  Uncaught ArgumentCountError: Too few arguments to function VIWEC\INC\Email_Trigger::replace_subject(), 1 passed in /var/www/karmamiacph.com/public_html/wp-includes/class-wp-hook.php on line 287 and exactly 3 expected in /var/www/karmamiacph.com/public_html/wp-content/plugins/woocommerce-email-template-customizer/includes/email-trigger.php:103

Can you please send me a previous version of your plugin, or fix it… Thank you.

P.s. It would also be great to be able to customise this e-mail type in the future 🙂

Best regards, Rasmus.
