Push notification to segment doesn't show on android while to single player works correclty

I would like some additional information, and I'll give you some general answers while I await confirmation.

• Which PlayFab SDK are you using? I assume based on Android device, that it is Unity, or Android Studio
• Which Push Plugin are you using? Our guides suggest that you use the device native FCM plugin, but I am aware that there are multiple 3rd party push plugins that will work as well.
  • If you are using the very old PlayFab push plugin, please note that we have discontinued that plugin (because it didn't really work very well), and suggest switching to the FCM plugin.
• Please indicate any other plugins or 3rd party software added to your project, and the version numbers for all relevant engine versions, PlayFab plugins, push plugin, etc.

The rest of this answer assumes that you're using a recent PlayFab SDK, a recent version of Unity or Android Studio, and the FCM plugin which is the device native plugin.

For Android, the client side plugin we suggest for our customers is the Firebase Cloud Messaging plugin, which is a 3rd party plugin, but the one recommended by the makers of the Android device. You may use any other plugin you wish, with the assumption that we are sending messages that follow the FCM messaging format. We don't support issues with the plugin itself, as we are not the providers of any push plugin.

You have indicated that the push notification displays when the app is running, but doesn't display when the app is closed. This tells me that the push notification is being delivered correctly to the device and your chosen plugin, and any issue with the message not displaying is a client-plugin problem. If there were an issue with PlayFab, the message would not display at all.

If you are writing your own plugin, receiving offline messages is done via an entirely separate mechanism than when the app is running. The mechanism for this has changed several times in the last year, and it's very hard to keep working with changing versions of the Android device OS. The only real plugin that does this properly across multiple device versions is the device native FCM plugin, which is why we recommend it.

In our guide, we suggest testing with messages sent directly from the Firebase Console. If you can correctly receive a message from the Firebase Console, but NOT from PlayFab under the same conditions, then post those conditions here for us to review, and we'll address the problem.

Thanks!
