I'm trying to test the payment gateway in Magento 2.1.2
I've set up a sandbox account in Braintree.
I've set it up in the Braintree section of stores > Configuration > sales > Payment Method.
I've tried test credit card values suggested by Braintree and Magento but nothing happens. I'm just trying to work out what I could be doing wrong. Maybe it doesn't work in Development mode?
Any ideas gratefully appreciated, Thank you
Simon
