Thanks. So I checked this on the demo using the ‘other’ product category. The custom field is visible during the order and is also visible in the admin panel after the order is completed.

But, i doesn’t appear in the client side panel for them to alter after the order is completed – it only shows the order details. This is what I really need, for the client to be able to see this and edit the fields when they need to.

I also tested it using a domain order and as you said the field is visible here, but there is no option to save/update. So even if they can edit the field it can’t be updated.

If this could be added to other orders and the ability to update added this would be perfect
