Notifications arrive, but text, icon, or content isn't showing up

Message rendering is misconfigured

Push notifications are delivered, but the content isn't rendering correctly — missing text, a missing icon, or a completely blank notification.

How to check

Review your onMessageReceived implementation and compare it against the setup instructions for Push Notifications Setup for Firebase.

If your code doesn't include a call to Mindbox.handleRemoteMessage, the notification isn't being rendered by the Mindbox SDK.

Note

If Mindbox.handleRemoteMessage is not called, Maestra has no control over how the notification is displayed. Debugging will need to happen on your end.

How to fix

Update your onMessageReceived implementation to match the Push Notifications Setup for Firebase guide.
