Hello, A user subscribed by in-app purchase subscription in the app "Target Leaderboard". We have got the transaction Id and base64 encoded receipt data in response. We can generate the JWT by the In-app purchase key file and key Id. But when we try to fetch all subscriptions by "https://api.storekit-sandbox.itunes.apple.com/inApps/v1/subscriptions" by passing the transaction Id, blank response is returned. Why it is happening?
Also, when we are try to fetch original transaction Id by "https://sandbox.itunes.apple.com/verifyReceipt" by passing the base64 encoded receipt data and SharedSecret, code 21003 is returned. Why it is happening? Please help.
