Incoming Notifications not collapsing.

[ghost]

Hello fellow partners. Im using cordova-plugin-fcm together as firebase Admin (NodeJS) , to send notifications to Android, iOS and Browser. Im not able to use any values besides data and notification because it seems the device is not reading it. This is my payload sent from the Server:

const messageOptions = {
                            contentAvailable: true,
                            priority: 'high',
                            timeToLive: 3,
                            collapse_key : 'demo',
                            data: {
                              event: event
                            },
                            notification: {
                              title: 'some title',
                              body: 'some body',
                              click_action: 'FCM_PLUGIN_ACTIVITY'
                            }
                          };

I manage to get the notification while in background and stuff, but they never collapse under the demo key.

Im using the latest version of the plugin @2.1.1. The only way I've managed to get notifications to collapse was using tag: 'demo' on notification object on the message payload. But that only works for Android and Browser.

Thanks in advance.

Okay, Ive figured it out. collapse_key : 'demo', , is working. If I set my iOs device to "airplane mode", and send 3 notifications with the same collapse_key, as soon I return the internet connection to the device It will only receive one. The problem is when I want to update a notification that already was delivered to the device.

eg. I send a notification saying that the user has a incoming call, if the user doesn't tap the notification I want to update it to "Call Lost". This is possible in Android and Browser by using the tag key in notification object. But I couldn't yet find a solution for iOs

Thanks in advance.

@nickmendes Did you find any solution for this? Going through the same issue. I want to avoid switching from fcm plugin as suggested by #291.

@dkarandi

you can't group notifications on iOS with fcm-plugin sadly :(

That sucks! Thanks for the quick reply though.
