We have a custom cart attribute setup on our cart page to capture a delivery date from customers.
We then pull this info out into our order confirmation emails as follows
{{ attributes.delivery-date | date: "%d-%m-%Y}}
This all works perfectly.
However… we really would like this information to also show on our packaging slip template, which we are struggling to do. We have tried the following codes without succsess
{{ attributes.delivery-date }}
{{order.note_attributes['delivery-date']}}
{{ order.attributes.delivery-date }}
