Hello, We have create a flutter based app on Wordpress. It has in app purchases as well. My app is getting rejected as because of the receipt issue as apple is unable to send notification our server. I need someone who has worked on in app purchases using flutter and WP so that they know where to set up this link. The freelancer will need to do it remotely connecting my system. Guideline 2.1 - Performance - App Completeness We found that your in-app purchase products exhibited one or more bugs when reviewed on iPhone running iOS 16.0.2 on Wi-Fi. - Specifically, the subscription page did not display the subscriptions. Next Steps When validating receipts on your server, your server needs to be able to handle a production-signed app getting its receipts from Apple’s test environment. The recommended approach is for your production server to always validate receipts against the production App Store first. If validation fails with the error code "Sandbox receipt used in production," you should validate against the test environment instead.
