I have setup PayPal Key and made payments with it and love it. However, I have 2 cards with matching last 4 digits and 2 others with a different matching 4 digits. When adding the cards I've given them nicknames to I can distinguish between them. However, when attaching them to PPK, the nicknames are not displaying on that page. Am I missing a setup step, or is this something to email PayPal about?
