meteor $pull remove from array

I have the following object in my database:

{
    "_id": "fTgR2YtHiZBzzqF6J",
    "following": [
        {
            "user": {
                "_id": "S4dLHRJiuHoyAp26q",
                "fb": {
                    "id": "100006681067911",
                    "name": "Helen Amffhajfgiaa Laubergskymanwitzescusonsteinsen"
                }
            },
            "date": "2013-10-01T17:25:50.305Z"
        },
        {
            "user": {
                "_id": "MAyxz4Yk5F9vh9RRy",
                "fb": {
                    "id": "100006719587007",
                    "name": "Mary Amfgaiehgkg Smithman"
                }
            },
            "date": "2013-10-11T10:47:58.898Z"
        }
    ]
}

Now I want to remove the

{
   "user": {
      "_id": "MAyxz4Yk5F9vh9RRy",
      "fb": {
          "id": "100006719587007",
          "name": "Mary Amfgaiehgkg Smithman"
      }
    },
    "date": "2013-10-11T10:47:58.898Z"
}

subdocument from the array called "following".

My query to do this looks like this:

 Collection.update({"_id":"fTgR2YtHiZBzzqF6J"},
 {
    "$pull": {
        "following": {
             "user": {
                 "_id": "MAyxz4Yk5F9vh9RRy"
             }
         }
     }
 });

But nothing happens!

Can someone point me towards my error?

You can also try this answer (Remove Item from Array in Meteor.js), I think it's a better fit, with less code.

My problem was: I had to $pull the whole object:

 Collection.update({"_id":"fTgR2YtHiZBzzqF6J"},
 {
    "$pull": {
        "following": {
            "user": {
                "_id": "MAyxz4Yk5F9vh9RRy",
                "fb": {
                    "id": "100006719587007",
                    "name": "Mary Amfgaiehgkg Smithman"
                }
            },
            "date": "2013-10-11T10:47:58.898Z"
        }
         }
     }
 });

and can NOT just call this:

Collection.update({"_id":"fTgR2YtHiZBzzqF6J"},
 {
    "$pull": {
        "following": {
             "user": {
                 "_id": "MAyxz4Yk5F9vh9RRy"
             }
         }
     }
 });

The problem is exactly the same as https://stackoverflow.com/a/17779687/149818. You query in general right and would be work just for case if you have exactly 1 "user", but for multiple users you have to redesign your collection
