应用内购买：自动续订订阅流程

Question

我已将月度订阅集成到我的应用程序中，为此，我在应用程序购买中使用了自动更新功能。 SandBox构建一切正常，但是通过TestFlight测试构建时，我面临两个问题。

1. 成功购买后，应用程序仍要求我确认我的Apple ID密码，并显示消息“ 输入Apple ID xxxxxx.xxxx.xx的密码，以验证iTunes帐户并允许该设备确认购买。 ”
2. 删除并重新安装该应用程序后，我试图购买上一个项目，并且该应用程序显示一个弹出窗口，显示 “您当前已订阅..........管理。确定。 “ ，当我点击“确定”时，什么也没有发生。我认为，此时应使用 TransactionStatePurchased 调用“ updatedTransactions” 委托，但没有任何反应。或可能正在发生某些事情，但我不知道如何在TestFlight构建中对其进行调试。

我已将事务观察器添加到AppDelegate
