I'm using ConnectyCube Flutter to implement video call functionality in my Flutter app.
The call notifications work fine on Android, but on iOS, I don't receive any notification when a call is initiated from another device.
What I Have Done So Far:
- Configured Push Notifications:
- Set up Firebase Cloud Messaging (FCM) for push notifications.
- Uploaded the APNs certificate to ConnectyCube.
- Checked iOS Permissions: Enabled Push Notifications capability in Xcode. Ensured NSUserNotificationAlert is added in the Info.plist.
Tested with Background & Terminated State: On Android, the notification is received properly. On iOS, no notification appears in both foreground and background states. Debugging Logs: No errors related to push notifications appear in the logs. Verified that FCM token is correctly generated on iOS.
below is my AndroidManifest file

I'm using ConnectyCube Flutter to implement video call functionality in my Flutter app.
The call notifications work fine on Android, but on iOS, I don't receive any notification when a call is initiated from another device.
What I Have Done So Far:
- Configured Push Notifications:
- Set up Firebase Cloud Messaging (FCM) for push notifications.
- Uploaded the APNs certificate to ConnectyCube.
- Checked iOS Permissions: Enabled Push Notifications capability in Xcode. Ensured NSUserNotificationAlert is added in the Info.plist.
Tested with Background & Terminated State: On Android, the notification is received properly. On iOS, no notification appears in both foreground and background states. Debugging Logs: No errors related to push notifications appear in the logs. Verified that FCM token is correctly generated on iOS.

Reset to default 0At first need to check the guide how to configure Push Notifications. After all setup check with some of call samples. Also take a look at similar issue at github issue
But again, it's important to look at official guide and double check all needed configuration settings.
