ios - How do you change the app store's large icon on iTunes connect?

Question

I need to change the large app icon (512x512) for app store. I can't find how to to this through iTunes Connect. I's possible change the app screenshots though. I read the iTunes manual (page 97) and it says that it can be done but I only have the "choose file" button for screenshots, not for the large icon.

I am also confused because the same manual says on on page 99 that edit-ablity of the large icon is locked.

What am I missing?

Answer 1

Yes, editing of large icons that are already in use by iTunes Connect is locked, but however, You can still register a new update to Your app, in which You can upload Your new 1024*1024 icon
