Following request to the REST API
https://sandbox.dev.clover.com/v3/apps/appId/merchants/mId/billing_info
returns information about the appSubscription and a field 'subscriptionCountries' containing one element (at least at my tests). Since the field is named in plural I wonder if it really can have more than one element? It would mean that a merchant has e.g. 2 subscriptions, e.g. one in the US and another in Canada. But as far as I know a merchant is always only located in one town. Is it for travelling salesman? How are, by the way, merchant ids assigned if a company has 100 salesmen who travel across the country? It wouldn't be a good deal for an app developer if one could only sell one subscription to such a company if they had only one merchantId.
