If I want to create an application or do something like it on the Itunes Connect portal, I am sent to this page:
https://developer.apple.com/register/error/
"You've already agreed to the Apple Developer Agreement".
It proposes links to "Continue with Member center" or "Sign Out". Nothing else can be done.
Continuing to Member Center doesn't work - it only gives the same page again.
Signing out works but the same scenario then applies again.
I've tried with other computers and navigators, including a Windows and a Mac.
The error is present with all navigators (including Safari).
Others have been mentioning this error at other places (stackoverflow etc) but have been booted out since it looks so much like a "registration error".
The account is clean and with accepted agreements.
It looks like an iTunes Connect error.
We get more and more of these things and bugs lately.
