You are getting this error because ITC has recently changed rules for uploading Screenshots.
Here are few things you should keep in mind :
iPhone:
- For iPhone you must upload 1 set of screen shots for 5.5 inch device (1242x2208 size)
- Kindly take a note that 1 set means you can upload 5 screenshots
- You can upload screenshots of other devices from media manager. But only if your application have localization feature & you need to show other language screenshots
iPad:
- For iPad you must have to upload 5 screenshots of 12.9 inch iPad device. (2732x2048)
- You can upload screenshots of other devices from media manager. But only if your application have localization feature & you need to show other language screenshots
Now in your case i can see you are trying to upload iPad retina screenshots but its giving you error message.
Simply follow this things:
- Ask designer to create one splash screen for 2732x2048 size & upload it. As because we can add minimum 1 screen shot so you will be submit the application by 1 screenshot only.
- If you have added other device screenshots from media manager than make sure you have localization feature & in that case you have to select other language. Other wise remove that screenshots.
Important Note:
- I already tried the same solution & got approval for my app. So its a tried & tested solution & its not on basis of assumptions.
Hope it will help to everyone.
