Hello Anca,
I checked for the respective selector and found it to be, i believe, order_comments, (see screenshot here so you can confirm if right). Besides, data-no-translation appears to be there already?
I added it to exclude strings but the text keeps getting translated.
I searched it on the string translation interface to get it deleted, but i didn’t get any results, so possibly it’s the reason it keeps getting translated.
On the body of the email, I also noticed that the names of the products get translated “twice” (TP already translated them on their respective pages but the translation on the email don’t match) and the footer too with our company name getting translated.
Any advice why this is happening?
