Images can't contain alpha channels or transparencies., alphachannels

During the last two days, the iTunes Connect update was prepared to send a new app. I found that the upload icon always reported the above problem. I checked whether the previously uploaded icon was uploaded again, jpeg has no alpha channel. You can save the image as jpeg and upload it. Alternatively, you can deselect the alpha check box when saving the png image.
