I'm using Braintree on a basic Spree 3.0.0 installation.
I created an sandbox account and added the merchant id and key's in the Admin panel for Braintree. I am able to complete an order all seems OK but in the Order section the payment state will have the status balance due. This is common behavior? Should not be changing to "paid" ?
Isn't Braintree confirming the transfer of funds even if it's a sandbox env. ?
