I was finally able to get it to submit. Make sure to set the Pricing and Availability information even for free apps and then save and try to submit for review.

I am also getting the same error message: An unexpected error was encountered when submitting for review. If the issue persists please contact us I have tried everything: Create a new build 4 times Created an entirely new app and build Update xCode and Rebuild Changed settings, checked certs, profiles, keys -- everything and no luck If you open up the inspector the response returned is: {status: "500", code: "UNEXPECTED_ERROR", title: "An unexpected error occurred.",…}

I have the same issue
