Unable to submit iOS app for review - “There are one or more errors on the page.”

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.

Answer 1

I had uploaded a new app v1.0 which got rejected. I updated the version to 1.0.1 in the plist and selected the correct version on App Store Connect. The problem I had was that my original app version was manually still listed as 1.0.

Changing that to 1.0.1 solved my problem.
