Same here. Is this plugin dead?
Seems to be working for me, but I haven’t set anything under the scope section. Instead I’ve only set the currency (USD, EUR, etc) in the wise payment setup and rely on my currency switcher plugin to select the correct currency (or let the user select which currency they want to pay in). So far it seems to be displaying the correct wise account for the matching currency.
Something I did notice is that in the plugin setup area there’s 3 hyperlinks “Countries | Continents | Currencies“, but the hyperlinks for Countries and Continents are dead. The current links point here: “https://github.com/woocommerce/woocommerce/blob/master/i18n/“, but I think they need to point here: “https://github.com/woocommerce/woocommerce/tree/trunk/plugins/woocommerce/i18n“. The bigger updates to wordpress/woocommerce over the last 10 months could have moved some files around and may be a possible source of these issues, but I’m not a developer so I don’t know.
