Silent notification is not working in iPadOS. But, in 12.4 OS it is working fine.
{
"aps": {
"content-available" : "1"
},
"BuildingId":13,
"NotificationTypeId":214,
"CustomerName":"Test",
"Amount":"6778",
"CustomerID":32752,
"Environment":"TEST",
"Title":""
}
"apns-push-type" is Required when delivering notifications to devices running iOS 13 and later, or watchOS 6 and later. Ignored on earlier system versions. Apple document APNS Silent push notification.
Adding "apns-push-type" header field solved the issue. Please note this is a APNS POST request header field, not a new key in push JSON.
