Ionic Push Notification not even sent to iOS (let alone received) on production

Question

I have an issue with Push Notification for iOS in production mode.

I first developed Push for development:

created dev provisioning profile on Mac
created dev certificate on Mac
created a dev security profile in Ionic Dashboard
added dev certificate to dev security profile Ionic dashboard

All worked fine for Android as well as iOS.

I then switched to production:

created provisioning profile and certificate for live on Mac
created a live security profile in Ionic Dashboard and added live certificate

I always test Push using Postman:

send POST to https://api.ionic.io/push/notifications with body:

{
    "tokens": [
        "<ios token>",
        "<android token>"
    ],
    "profile": "live",
    "notification": {
        "message": "test",
        "ios": {
            "priority": 10
        },
        "android": {
            "priority": "high"
        }
    }
}

response:

{
  "data": {
    "status": "open",
    "config": {
      "profile": "live",
      "notification": {
        "android": {
          "priority": "high"
        },
        "ios": {
          "priority": 10
        },
        "message": "test"
      },
      "tokens": [
        "<ios token>",
        "<android token>"
      ]
    },
    "created": "2017-02-14T15:07:58.988762+00:00",
    "app_id": "<app id>",
    "uuid": "<uuid>",
    "state": "enqueued"
  },
  "meta": {
    "status": 201,
    "request_id": "<request id>",
    "version": "2.0.0-beta.0"
  }
}

To see what's going on, I always send a GET afterwards to https://api.ionic.io/push/notifications/‍<uuid>‍/messages (uuidfrom the first response) and get the following response:

{
  "data": [
    {
      "status": "sent",
      "created": "2017-02-14T15:07:59.165266+00:00",
      "user_id": null,
      "token": {
        "token": "<android token>",
        "valid": true,
        "type": "android",
        "app_id": "<app id>",
        "invalidated": null,
        "id": "<id>",
        "created": "2017-02-14T14:27:27.585235+00:00"
      },
      "error": null,
      "notification": "<notification uuid>",
      "uuid": "<message uuid>"
    }
  ],
  "meta": {
    "status": 200,
    "request_id": "<request id>",
    "version": "2.0.0-beta.0"
  }
}

I noticed that the data for the corresponding <ios token> is missing in the response.
I'm wondering why there isn't even an error response as listed at Ionic Docs.
If I send both requests using the dev security profile I get data for iOS stating "error" (APNS_BAD_DEVICE_TOKEN) - which is correct.

I already tried re-creating the certificate and stuff, which does not change the result. I also waited a whole day to receive a notification, in case something takes really long. I made double sure I built the app with the correct profiles in Xcode.

I'm using Xcode 8.2 by the way - and definetly made sure to enable "Push Notifications" in capabilities.

What am I missing?

After contacting the Ionic Support they brought up the idea to check for the tokens being valid.

The How-To is documented in their docs:

(GET) https://api.ionic.io/push/tokens/:token_id (where token_id is a md5 hash of the device token)

I added a Pre-request Script in Postman for that like:

var token = "<your-device-token-to-check>";
var hash = CryptoJS.MD5( token ).toString();
postman.setEnvironmentVariable('token_hash', token);

... and added the new environment variale as a Parameter (not in the Request URL) as key: (leave empty); value: ":{{token_hash}}"

I then found out, that all my iOS tokens were invalidated shortly after they were registered. That's how our first tests succeeded and at further development suddenly failed.
I don't know why they are then left out on the response, when checking for notification status against the Ionic API. I suggested the Support to add an error response (as I understand it, there already is one: 'APNS_BAD_DEVICE_TOKEN' as "The specified device token was bad. Verify that you specified a valid token [...]".)

Because I cannot explain why, I just re-created new profiles and certificates (again!), and deleted the old ones from the Keychain Access on the Mac. I re-built the app and everything went fine. Weird...
