When trying to upload an archive to the store from the Organizer window, I get the message in the title.
I just upgraded from xcode 9 beta to the GM seed. It worked before that. Note that I had the same issue with the beta version initially but the issue resolved magically after talking with support that couldn't help me.
I have already tried multiple times to remove/add my itunes account. Also tried to revoke certificates to regenerate new ones.
Might even be a caching issue?
Thankful for any help.🙂
