So we have a problem with our M2 site. We have a retail site and a trade site. We use Braintree. On the retail site customers are able to place an order fine using their debit/credit cards however on the trade site it is returning an error (attached) however it is taking payment. We are using two different Merchant ID's at first we had one and thought that was the problem however now we have two seperate ID's it still isn't working.
We really need to get this up and running however Braintree have said it isn't a problem on their end so something is going wrong in Magento.
