Your problem
I have no problem using {contactfield=…} tokens in text messages but {ownerfield=…} tokens are sent as (ownerfield=…). For example in text message I an inserting {ownerfield=firstname} but it is sent as (ownerfield=firstname) instead of real name or the owner. It just converts { to ( and send it as it is. Do you have any idea about this?
