How to wake up the application for push notifications? I'm using "content-available": 1 in the payload, xcode is configured (background fetch, remote notifications are checked), Notification Service Extension added. I am using firebase (admin-sdk, NodeJS). notification: {     title: 'some title',     body : 'somebody' }, data: { command:notification.command,     ...data },     apns: {          payload: {                aps: {                     contentAvailable: true                     mutableContent: true                     sound: 'default',                }          },          headers: {                    'apns-push-type': 'background',                    'apns-priority': '10',                    'apns-topic': 'login.topnlab.ru',      }, }, Push notifications come in foreground, quit, background state, but not in killed/terminated. The app only wakes up if the push notification is delivered immediately after killing the app and within a couple of minutes. And the application does not wake up until the user launches the application. I understand that firebase doesn't guarantee stable delivery of remote push notifications. But now the app doesn't react at all on them. It looks like I'm doing something wrong. Give me a hint, please, where could I be wrong?
