Notification on iOS

When calling a Create Payment API "MATCH_USER", I do not receive any notification on my iPhone.
I need to open Satispay (staging) app and then I am prompted to confirm the payment, which I approve /reject correctly.
Is this normal? Is it related to the "staging" app? Apparently no, because nofifications are full ON and authorized on my iPhone.
Is it related to my CreatePayment payload?
