Thank you for quick reply.
Yes, it was exactly, as You say. Problem ended when I just deleted free plugin.
customer.phone will not help in my case (they checkout without creating account), but looking forward fororder.billing_phone . Hope will have it soon 🙂
unfortunately, there is no such placeholder in placeholder section, if even I use order based event (order status changed -see screenshot attached on this link https://mega.nz/file/oLJAEaKK#VaUnLa6584nn1mv9-HZQul6YUi9Pi8qnyyJrd16LjJg )
If I just write {{ order.billing_phone }}, it returns empty – no any record in it.
I am using a free version of ShopMagic, I have to say. Maybe that is a reason ?
