Background of the issue:
I use Woocommerce Bookings for my services and I need help with my booking confirmations emails. By default, the customer receives 2 emails (each one for the site's languages). If I put some text in the pending confirmation email's fields from Woocommerce settings, it doesn't seem to interact with WPML. I have already seen the issue below but nothing seems to change by putting this function in my theme's file: https://wpml.org/errata/woocommerce-bookings-multiple-booking-confirmation-emails-sent-for-each-language/
Symptoms:
The customer receives two booking confirmation emails, one for each language, and the pending confirmation email's fields from Woocommerce settings do not interact with WPML.
Questions:
How can I prevent customers from receiving two booking confirmation emails for each language?
Why doesn't the text in the pending confirmation email's fields from Woocommerce settings interact with WPML?
