I've set 2 websites us and uk.

Signed up for Braintree sandbox account.

Created 2 Merchant Account ID.

1- uk_maid currency GBP.

2- us_maid currency USD.

Magento admin Stores->Configuration->Sales->Payment Method on the left changed Store View: uk_website then configured Braintree entered all details plus Merchant ID = uk_maid saved.

Again same process as above but Merchant ID will be us_maid:

Magento admin Stores->Configuration->Sales->Payment Method on the left changed Store View: us_website then configured Braintree entered all the details and Merchant ID = us_maid saved.

Placed order in uk website everything works payment were taken and appear in my sanbox Braintree dashboard under the uk_maid which is set to default.

Now using us website in ../checkout/#payment as soon as check radio box Braintree as payment option :

In console:

I don't get it why can't use alternative merchant id for us website?

Is this a bug? Anyone have had this set up any experienced the issue? Thanks.
