In this case, I used my project project to export the ipa to testflght. The tester installed the app on the test device, started the app, and received the payment voucher information pushed by storekit. At this time, the test device did not log in to the sandbox account. Of course, The test device has previously logged into the sandbox account and successfully paid for the subscription. When I used the same test device, connected to Xcode, clicked run, and ran the app, I did not receive the payment voucher information pushed by storekit. I am very confused, why does testflight receive the certificate information pushed by storekit?
