我正在尝试使用SKPaymentQueue.default（）。restoreCompletedTransactions（）恢复非消耗性IAP，但按照计划没有任何效果。在沙盒中，我收到“没有可用的应用内购买信息。请稍后再试。21105”，在Prod中，什么也没有发生。从我可以看到，实际的SKPaymentQueue.default（）。restoreCompletedTransactions（）行引发了沙箱中的错误，此后未进行任何处理。我确信一切都正确，因为我可以手工购买并且可以正常使用，所以我也可以再次购买任何有错误的东西，即我已经拥有它，然后激活该项目，但是“还原”按钮不起作用（restorePurchases（）） 。我的应用程序中确实有38个IAP，但是我不确定这是否以任何方式关联，并且它们都是非消耗性的。出售贴纸的是iMessage Extension。另一个奇怪的是，Apple确实取消了我的应用程序，因为我在未经我自己许可的情况下使用了自己的Art（这很有趣），但是所有情况都表明，使用非消耗品必须具有Restore（还原）功能，Apple对此进行检查。情况一切都在不工作的情况下通过了。
我的IAP类别是：
import Foundation
import StoreKit
import os.log

我做错了什么，如何使RestorePurchases实际执行某些操作？
