title: Unable to Post to a Feed Group in GetStream
body: <p>I'm currently using Stream to build Feeds in our React Native app.</p>
  
  <p>I ran into a problem enabling users to post to a new board feed group I made.</p>
  
  <p>Currently iOS only</p>
  
  <p><strong>Problem:</strong> I have created a "board" feed group and want to allow users to post to that feed group to save posts. I have enabled permissions for this as per: <a href="https://github.com/GetStream/react-activity-feed/issues/23" rel="nofollow noreferrer">https://github.com/GetStream/react-activity-feed/issues/23</a> via support. Yet I am still unable to post to the "board" feed group but I'm still receiving a permissions error.</p>
  
  <p>I'm using the SinglePost component from the official React Native GetStream library and have a save button on the activity component.</p>
  
  <p>The save button opens a modal to allow a user to select a board and after a user selects a board the _saveBoard method is called. You can see the full method here.</p>
  
  <pre><code> _saveToBoard = item =&gt; {
      let boardId = item.id;
  
      console.log('boardId', boardId, this.props);
  
      // // Add activity to selectedBoard
      var selectedBoard = this.props.client.feed('board', boardId);
  
      let activity_data = {
        actor: this.props.client.currentUser.id,
        verb: 'save',
        object: `BoardPost:${generateId()}`
      };
  
      console.log('activity data', activity_data);
  
      selectedBoard
        .addActivity(activity_data)
        .then(res =&gt; console.log('added activity', res))
        .catch(err =&gt; console.log('error adding activity to board', err));
  
      console.log('selectedBoard', selectedBoard);
    };
  </code></pre>
  
  <p>Not sure where I went wrong and hoping its something I overlooked.</p>
