推荐答案

我遇到了与您看到的相同的问题

I had the same problem as you can see here.

我在此处的注释中找到了此讨论.事实证明，在FCM中订阅主题不一定是永久的.因此，请勿一次向用户订阅主题.尽管它是每次启动，但都应在每次应用启动时都这样做

I found this discussion in the comments to this answer here. Turns out that subscribing to a topic in FCM is not necessarily permanent. So don't subscribe users to a topic once. Instead do it on every app start, although it is

"在技术上不是必需的.这可能取决于您的用例.为了例如，如果您想要一个全局主题，其中所有用户都是该主题的成员，您必须确保他们已订阅.把应用启动时的订阅方法可确保这一点."

"not technically necessary. It may depend on your use case. For example, if you want a global topic where all users are a member of, you'd have to make sure that they are subscribed to it. Putting the subscribe method when the app starts guarantees this."

就我而言，这为我解决了问题.现在，通知的接收人比以前更多了.只有未结清帐户仍然对我不起作用.始终为零.

In my Case this fixed it for me. Now the Notifications are received by a lot more people than before. Only the open-count is still not working for me. It is always on zero.
