Messages received without Notifications even background fetch is turn off

Can you provide me some explanation about how to achieve received messages in terminated mode without showing any notification and turn off background fetch in settings ?

In whatsapp application if I mute any conversation and from settings turn off background app refresh , turn off notifications , after when sender send messages , he got delivered response , when I turn-off my internet and open whatsapp application that all 60-70 any number of messages are already received !

I tried with background silent push with FCM but soon if I open any other application , I'm not able to getting silent push. I tried with all versions from iOS 13.5 to iOS 14.3 but all have same output.

How to achieve to load/insert data in terminated application , with turn off background app refresh , notifications ?

there is no reply by apple support.

Does that mean you opened a DTS tech support incident (TSI) about this and we didn’t respond there? Or are you saying that no one responded on the DevForums thread you referenced?

To be clear, DevForums is an informal support channel. Any Apple folks who respond here are doing so subject to their (many) other commitments. If you want a formal support, you should open a DTS TSI.
