CAR: Deprecated legacy notifications

Description

Google has deprecated the legacy version of the Firebase Cloud Messaging (FCM) protocol for sending push notifications.
Push notifications for Android are now sent using Firebase Cloud Messaging (version 1)APIs.

We recommend updating your Foundation applications that send push notifications for Android devices by 20 June 2024.

In fact, after this date the Firebase Cloud Messaging (legacy) APIs will stop working, and consequently mobile applications will no longer receive notifications.

To enable the new notification type, you'll need to set the new JsonKey property (which replaces the previous ApiKey) with data in JSON format obtained from the Google console.
More information available in the online JsonKey property documentation.

In addition, the CollapseKey property has been added in order to indicate that a group of messages can be collapsed.

Beginning with version 24.0, push notifications are sent using the new protocol, so you'll need to convert your projects to that version and republish applications to the store..

To learn how to configure the system to be able to send push notifications, we invite you to read the article for the IDNotification library.
