title: Unity dotween delay before the next append not working
body: <p>I have lists of data and I am trying to tween them by sequence. If I put a delay for each of the tween it will not work. What I try to achieve is inserting the delay before the next sequence.</p>
  
  <pre><code>private IEnumerator&lt;float&gt; _CameraTransition()
  {
      var camSequence = DOTween.Sequence();
  
      for (int i = 0; i &lt; CamerasData.Count; i++)
          camSequence.Append(cam.DOFieldOfView(CamerasData[i].fov, CamerasData[i].duration).SetDelay(CamerasData[i].triggerDelay));
  
      camSequence.Play();
      yield return 0;
  }
  </code></pre>
  
  <p>If I remove the <code>SetDelay</code> it works, but of course no delay</p>
