About 1 or 2 times a day our magento 2.1.8 store fails to do a transaction via braintree leaving the message Cannot determine payment method in the debug.log
After contacting braintree they said this was due to the payment method none not being sent across, however it is being sent 96% of the time.
If you percavere and keep entering your details the payment will eventually go through however this seems like quite a big bug with in the native brain tree integration, has any one else come across this before or know of a fix/patch?
