What size screenshots should be used for IAPs ( In app purchases ) for Mac apps? : <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>
