I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

any updates?

Hey @jedai7, sorry this took a while. Upon testing, it seems that this also happens on native iOS. Could you file an issue to the Firebase iOS SDK?

For context, the Firebase Unity SDK acts as a wrapper, and if the underlying SDK encounters the issue, then the fix would likely be applied on the native SDK.

That said, I'll go ahead and close this thread. Feel free to reply back here in case of any updates. Thanks!

Hi @jedai7, our colleagues informed me that it could be an issue specifically with our Unity SDK. Let me investigate this further and reply back once I have updates to share with you.

Just some updates, it looks like in iOS there are extra setups needed to get the image to show in Firebase Messaging. Specifically adding, this code snippet.

Now for Unity builds, while I think it is possible to add Notification Service Extension with Xcode after exporting the iOS project. The FCM docs for Unity does not specify how to add the following equivalent code in didReceiveNotificationRequest

@implementation NotificationService

- (void)didReceiveNotificationRequest:(UNNotificationRequest *)request withContentHandler:(void (^)(UNNotificationContent * _Nonnull))contentHandler {
    self.contentHandler = contentHandler;
    self.bestAttemptContent = [request.content mutableCopy];

    // Modify the notification content here as you wish
    self.bestAttemptContent.title = [NSString stringWithFormat:@"%@ [modified]",
    self.bestAttemptContent.title];

  // Call FIRMessaging extension helper API.
  [[FIRMessaging extensionHelper] populateNotificationContent:self.bestAttemptContent
                                            withContentHandler:contentHandler];

}

Let me bring this up to our engineers and see if we have an official guide for setting this up.

Hey @jedai7, it looks like we don't have this feature available yet for Firebase Unity SDK. I've consulted this with our engineer and have concluded that we likely need to add an equivalent C# code for this feature. That said, we are unable to promise any timeline for this, but we'll definitely keep this under our radar.
