Fatal error: Uncaught ArgumentCountError:

Since installing the Woocommerce Email Template Customizer, I have not been able to generate an email for the “delivered” order status (which reads as “Geliefert” on my site because the site is german), instead I get the following error message:

Fatal error: Uncaught ArgumentCountError: Too few arguments to function VIWECINCEmail_Trigger::trigger_recipient(), 2 passed in /homepages/31/d649026086/htdocs/clickandbuilds/MFPDeutsch/wp-includes/class-wp-hook.php on line 287 and exactly 3 expected in /homepages/31/d649026086/htdocs/clickandbuilds/MFPDeutsch/wp-content/plugins/woocommerce-email-template-customizer/includes/email-trigger.php:62 Stack trace: #0 /homepages/31/d649026086/htdocs/clickandbuilds/MFPDeutsch/wp-includes/class-wp-hook.php(287): VIWECINCEmail_Trigger->trigger_recipient(‘{customer_email…’, Object(AutomatticWooCommerceAdminOverridesOrder)) #1 /homepages/31/d649026086/htdocs/clickandbuilds/MFPDeutsch/wp-includes/plugin.php(212): WP_Hook->apply_filters(‘{customer_email…’, Array) #2 /homepages/31/d649026086/htdocs/clickandbuilds/MFPDeutsch/wp-content/plugins/woo-advanced-shipment-tracking/includes/emails/class-shipment-delivered-email.php(54): apply_filters(‘woocommerce_ema…’, ‘{customer_email…’, Object(AutomatticWooCommerceAdminOver in /homepages/31/d649026086/htdocs/clickandbuilds/MFPDeutsch/wp-content/plugins/woocommerce-email-template-customizer/includes/email-trigger.php on line 62

Please may you help me with this issue.

Thanks in advance!
