+# 55. iOS FCM routing
+
+Date: 2024-12-05
+
+## Status
+
+Accepted
+
+## Context
+
+- Notification from FCM contains `mutable-content: true`
+- Those notification will be transfered to Notification Service Extension ([See here](https://developer.apple.com/documentation/usernotifications/modifying-content-in-newly-delivered-notifications#Configure-the-payload-for-the-remote-notification)) whether the app is in background or foreground
+- Due to the app is in foreground, no notification will be shown
+- Due to NSE handle the data, FCM on Flutter side cannot handle it
+
+## Decision
+
+- We check if the app is in foreground or not
+  - If the app is in foreground, we will not modify the payload and route the payload to FCM foreground method channel
+  - If the app is in background or terminated, we will keep the current implementation
+
+## Consequences
+
+- Twake Mail iOS app will get latest updates when app is in foreground
