Hey! The old editor is out of the question since it will be unavailable from january 2021. I tried using different product templates instead of service but the confirmation email prints text to the same location with all the settings.
Service product: "We will be in contact shortly regarding the services you have ordered."
Product: "We will notiify you shortly when the order has shipped" (or something like this, I did not write it down).
...there's also no way to translate this phrase 😞
