title: Cannot set app icon with transparency to iTunes Connect
body: <p>iTunes Connect has been updated in the last few days, now when I try to update App Icon (not screenshot) I get the following error:"Images can't contain alpha channels or transparencies."</p>

  <p>I had no such trouble in the past, has Apple changed its guideline on app icon or is this perhaps a bug in the new site? If the guideline has been changed, is the solution to simply remove any transparency?</p>
