body: <p>What dimensions should be used for IAP screenshots for Mac apps on iTunesconnect?</p>
  
  <p>I have tried uploading PNG screenshots with:</p>
  
  <pre><code>2560 x 1600 px
  640 x 920 px
  </code></pre>
  
  <p>to no avail... but the upload does not seem to be accepted... Can anyone advise which dimensions will be accepted? Apple specifies 640 x 920 but it does not upload and there is no error message.</p>
