Thank you for the device logs suggestion. My extension is getting launched for sure. Then saw this in the logs: "[Bundle id] Received remote notification request <> [ waking: 0, hasAlertContent: 1, hasSound: 1 hasBadge: 0 hasContentAvailable: 0 hasMutableContent: 1 pushType: None]" "[Bundle id] Notification filtering will not be allowed because the push type 'None' is not 'Alert' " Suspecting the push type sent from my server to the APNS. Will update the findings.
