我在我的应用中设置了订阅产品，它适用于购买。我在google开发者控制台中看到了这次购买。当我退出然后返回应用程序时，我再次进入订阅页面。该应用无法识别订阅已购买且应允许用户访问。如果我再次单击订阅按钮，它会说＆＃34;您已经订阅了...管理订阅。＆＃34;我不确定需要做什么才能使用户在验证订阅后将用户发送到订阅的信息，或者拒绝未找到订阅并将用户发送到订阅页面。我想我还没有知识如何建立它。这是我的代码。我错过了一大堆可以处理的代码吗？
我使用firebase作为注册/登录的后端。不确定我是否需要使用firebase来保存令牌等。任何帮助将不胜感激。我知道我是一个新手和学习者，但我的项目完成了98％，这让我退缩。
