title: Instagram API doesn’t find any liked posts for sandbox users
body: <p>I’m using the Instagram API in sandbox mode. I’m trying to access a User’s liked posts from the Instagram API using their authenticated access token. This user is one of the accepted sandbox users for my app, and has liked some posts.</p>
  
  <p>If I call other endpoints with the same token, I get some data, but accessing <code>/users/self/media/liked</code> returns empty data.</p>
  
  <p>I’m using this URL:</p>
  
  <pre><code>https://api.instagram.com/v1/users/self/media/liked?access_token={verified access token}
  </code></pre>
  
  <p>and this is the result I’m receiving:</p>
  
  <pre><code>{"pagination": {}, "meta": {"code": 200}, "data": []}
  </code></pre>
  
  <p>Because it has a 200 return code, the access token is valid. So why don’t I see any liked posts?</p>
