Notifee does snot handle FCM, that's @react-native-firebase/messaging

And delivery when killed on iPhones, for data-only messages is terrible, you will likely never receive messages on iOS that are data-only. They cannot ever be relied on. You have to include a notification block

but why i am getting it in iphone 12 pro? with same payload

Because iOS will tempt you into thinking it is reliable in certain cases, so you start using it, only to find it fails. Trust me please, do not ever rely on data-only messages for communications with iOS devices.

Here is a short list of reasons iOS will decide not to deliver message:

• the user has disabled background refresh
• the user is in low power mode
• the user's battery is low by some sort of arbitrary amount measured against how much the user uses your app
• the user's device is overheating
• the user does not use your app much

You'll have no control. You'll file another issue like all of the other issues in the repository saying "I don't receive FCM on my iOS device sometimes" and you'll be disappointed. But there's no solution. You can't rely on data-only messages.
