I built a web application using the Apple Pay on the Web Interactive Demo with the Payment Request API, but encountered a few issues:
- The initiated web Apple Pay interface shows a spinning circle at the bottom and cannot proceed with payment（Bottom display:正在处理）. What could be causing this?
- How to set up sandbox testing for payments?
- How to asynchronously and synchronously retrieve payment results (backend code to fetch payment results)? The demo only shows frontend code using await response.complete("success"); for retrieving payment results
