I really like the look of the new smart buttons, but two issues:
1. There doesn't seem to be the same options as per the old buttons. For example, send buyers to a payment success page. Can I do this somehow?
2. I put one live on my website, selected pay by credit card, entered my details, pressed buy. A pop-up said payment was complete, but no payment was taken. Do I need to do something before making the button live?
