Unable to submit iOS app for review

Question

I wanted to submit my app for the App Store on iTunes Connect, but whatever I do I got this last message telling me there are still one or more errors on the page. Unlike earlier errors this error does not focus on a particular place on page, nor are there any red-colored fields.

Things I did:

• filled app info
• filled contact info
• uploaded screenshots for all supported sizes
• uploaded binary / selected on itunes connect
• filled rating form.

Here is the screenshot:

Answer 1

I fix the issue by adding a cover art. scroll down at the screenshot page and upload the cover art.

Answer 2

You should inspect the response from the apple server. The response contains a JSON. Search for "errorKeys", where it is not null or []. This way, you can find out the exact problem.

In my case it was saying "You must choose a version release option.", basically I needed to checkoff the pre-order option to expose the UI to select "Manually Release" option. After I selected that option, I checked back the pre-order option. This resolved the problem.
