Cursor Implicit Fetch doesn't work with reportstats.

For what it's worth, I've been using something like this as a wrapper.

<?php namespace PayPerClick\Market\Facebook\Data;

use FacebookAds\Cursor;

/**

        }
    }

    protected function advanceCursors() {
        if ($this->hasCursor($this->position+1)) {
            $this->getCursor()->rewind();
            $this->position++;
        } else if ($this->hasNextPage()) {

        $this->position++;

        $this->cursors[ $this->position ] = new Cursor($request->execute(), $objectPrototype);
    }

    }
