Pull replication with channels c# .net sync gateway

Mobile Couchbase Lite

I am having trouble replicating documents using channels. I am testing a case where I have pushed documents through sync gateway. Then I delete the database, or use another device, and try to pull those documents for that user. When I query documents that should have been pulled, I get 0 documents returned. My set up is as follows: each user has a channel in sync gateway. This is assigned when the user registers with the sync gateway. Then, when the pull replication is set up, I set the channels according the the user id.

    Push = db.CreatePushReplication(uri);
    Pull = db.CreatePullReplication(uri);
    var auth = AuthenticatorFactory.CreateBasicAuthenticator(username, password);
    Pull.Channels = GetChannels();
    Push.Authenticator = auth;
    Pull.Authenticator = auth;
    Push.Continuous = true;
    Pull.Continuous = true;
    Push.Changed += OnReplicationChanged;
    Pull.Changed += OnReplicationChanged;
    Push.Start();
    Pull.Start();

where GetChannels is:

protected List<string> GetChannels()
{
    var channels = new List<string>
    {
        "ch_" + _userId,
        "public"
    };
    return channels;
}

Here is an example sync user who has assigned channels:

{
  "name": "john3",
  "admin_channels": {
    "ch_john3": 3
  },
  "all_channels": {
    "!": 1,
    "ch_john3": 3
  },
  "sequence": 3,
  "passwordhash_bcrypt": "X",
  "rolesSince": {}
}

and a document that has the channels property:

{
  "_sync": {
    "rev": "1-bf5b7541c1225d705b9603169266d8db",
    "sequence": 16,
    "recent_sequences": [
      16
    ],
    "history": {
      "revs": [
        "1-bf5b7541c1225d705b9603169266d8db"
      ],
      "parents": [
        -1
      ],
      "channels": [
        [
          "ch_john3"
        ]
      ]
    },
    "channels": {
      "ch_john3": null
    },
    "time_saved": "2016-11-06T04:23:22.241165778Z"
  },
  "channels": [
    "ch_john3"
  ],
  "date": "2016-11-06T12:23:22.476175+08:00"
}

Where am I going wrong?

The user and document channels look good - do you get the documents if you remove the channels filter (i.e. just retrieve all data that the user has access to)?

To get more information, you could enable Changes+ logging in Sync Gateway, and review the Sync Gateway logs for changes requests made by john3 - that will include some information about the set of channels being used for the changes request.

I looked at the logs and they seemed ok. I restarted sync gateway and it seems to be working now… strange.
