Hi,
I found a bug in Swift 1.21.1 one of the standard templates for the Integration Customer Center :)
The Templatetag used is this: Ecom:IntegrationCustomerCenter.Invoice.Link
But the link is actually in this templatetag: Ecom:IntegrationCustomerCenter.Invoices.Link
Template: Files\Templates\Designs\Swift\eCom\IntegrationCustomerCenter\InvoicesList.cshtml
