Using the example app, the notifications fails to show up. We get an error instead: 25 | Sync Subscriptions | Failed to parse incoming notification: [json.exception.out_of_range.403] key ‘event’ not found Everything else that exclude any other source of bugs are well tested, including the connection with Firebase and local notification for both IOS android.

Expected behaviour

A notification shows up on Message received.
