transactionReceipt is empty string when testing in app purchase on iOS.

[shuvajitmaitra]

I am trying to test my in-app purchase. After successfully purchasing the product in the app, via TestFlight and signing into the Sandbox account, I try and access the purchase.transactionReceipt value to send to my backend for verification, but it is an empty string.

Expected Behavior

It's expected not to be an empty string so that I can verify the transaction in my backend.

Screenshots

Environment:
"react-native-iap": "^14.0.1",
"react-native": "0.79.2",

Platforms (iOS, simulator, device): iOS Physical Device (TestFlight)
Is this because I am testing via TestFlight, so the transaction technically doesn't go through, thus there's no receipt?

You should use purchaseToken instead from 14.3.0 but I see you are using 14.0.1 so I am bit curious 🤔. Would you mind trying newer version? @shuvajitmaitra
