Hiya after downloading the latest version of the ACF Version 2.0.0, i deactivated the old version and deleted it, then uploaded this new version and activated it.
I actually deleted all the custom fields and created just a new one so now we have id = 2
i have tried again to set the shortcode in the emails
I also added this to the Checkout-Result page..
place some test orders and still not receiving this custom fields in the buyer or seller email.
we really need just one TEXT custom field to be added as we need an invoice number when we receive a payment.
We are very grateful in your time to sort this out, can we create an admin login for you (privately) so you can take a look at the settings etc.
