Now, my sendbird chat notification is not receive with android

The FCM token was registered properly, but no Android notification was received.
It is sent normally in the FCM console, but when using sendbird’s notification test, ’
Couldn’t send push notification.’
Something went wrong. ‘Please try again.’ is displayed.
I also entered the server key using the specified method, what is the problem?

Currently it says sent, but never actually arrives

Please refer to the article. I understand that data is not received in the background.

Currently, I know that this method does not work when there is only data and not notification, so I am wondering if it is possible to change the sending format to data → notification.

Hello @Yeonho_Jung ,

Could you please DM me the app-id and timestamp of the issue so that I can check the logs ?
