Hi，I am facing the 21002 issue.Have you went through it? If you have resolved it, please dive me a hand. Below is my code,and I Have tested in sand box environment. NSURL receiptURL = [[NSBundle mainBundle] appStoreReceiptURL]; if (![[NSFileManager defaultManager] fileExistsAtPath:[receiptURL path]]) { SKReceiptRefreshRequest receiptRefreshRequest = [[SKReceiptRefreshRequest alloc] initWithReceiptProperties:nil]; receiptRefreshRequest.delegate = self; [receiptRefreshRequest start]; return; } NSData data = [NSData dataWithContentsOfURL:receiptURL]; / receipt_data/ NSString *receipt_data = [data base64EncodedStringWithOptions:0]; After I test the purchase procedure, use the above receipt-data to verify on the server https://sandbox.itunes.apple.com/verifyReceipt,which always response 21002.I have no idea to deal with it.Thanks.

I am just developing an app,I just config the In App Purchase module in App Store Connect.And I have deployed the related code in flutter, and the Xcode have done the configuration about this. The fetching products is successful, and buyNonconsumable/buyConsumble api could be called successfully ,but whatever install methods I have tried, could not receive the receipt after call the buyNonconsumable/buyConsumbl api.So could you help to solve this problem,I just have stucked for a few weeks , please help. Btw ,my friends have told me that if I want to integrated the In App Purchase function,I need to upload a version to apple store and make it pass the review process.Please help me to confirm these question ,very thankful.

how could I remove the key NSMotionUsageDescription? cause it leads some crash problem.But after I remove the key NSMotionUsageDescription, I submit to Apple Store connect,I will receive issue .TMS-90683: Missing purpose string in Info.plist - Your app’s code references one or more APIs that access sensitive user data, or the app has one or more entitlements that permit such access. The Info.plist file for the “ydbus.app” bundle should contain a NSMotionUsageDescription key with a user-facing purpose string explaining clearly and completely why your app needs the data. If you’re using external libraries or SDKs, they may reference APIs that require a purpose string. While your app might not use these APIs, a purpose string is still required. For details, visit: https://developer.apple.com/documentation/uikit/protecting_the_user_s_privacy/requesting_access_to_protected_resources. How could I solve the problem? I reviewed my project,I don't use the key NSMotionUsageDescription api.
