@pahnpiseth this isn't enough information to tell what's going on here. Can you show more about how you're sending these messages? Is the behavior thee same if the device stays online the whole time?

[Xing1P]

i'm edited hope it enough info...please help.

[kroikie]

@pahnpiseth you mention

send with notification payload for background notification.
but if send without "notification" payload i receive notification is normal when send while device off internet and then device turn on internet.

Your example payload has a notification object defined. So is the problem happening with or without the notification payload?

[kroikie]

@pahnpiseth Note that notification-messages messages with a notification payload object are collapsed on the server by default if no collapse_key is defined. You can manually define a collapse_key to keep these messages from collapsing on each other. However you are limited on the number of concurrent collapse keys that the FCM backend will maintain.

Does this resolve your issue?

[Xing1P]

okay,brother mean when send message fcm with "notification" payload cannot use with non-collapse key?

[Xing1P]

okay,brother mean when send message fcm with "notification" payload cannot use with non-collapse key?

FCM document not mention this.

[macroday]

I have checked with and without collapse key but only last message come when turn on internet. Please tell me how to fix this issue or give some suggestion to fix it.
