My iOS app is using Firebase Cloud Messaging for push notifications.
Since Feb 2021, the send count for the notifications have reduced by more than 60%. We see a major drop in the number of sends.
Also, we have seen a drop in the notification_open event count on the Firebase dashboard. Most of the events are displayed as name = not-set in the console.
Any insights on the above behaviour is welcome. Thanks in advance.
Firebase team suggested that have an issue on their end and are working to fix the issue of notifications not being tagged.
ETA for the change was not provided.
