Game Center Xcode Problem

Just trying to added for review my latest app in apple connect and receive the message below.

"##### Unable to Add for Review

The items below are required to start the review process:

  • You must add the key in Xcode. Learn More"

The learn more link talks about adding the entitlement to the Xcode project ?

Everything works fine in development using Scotts Game Center plugin … any idea how to resolve as I don’t know how to add entitlements. by the way App ID is Game Center enabled and like I say works fine in development.

Any ideas ?

Apologies same problem as another thread

so please close.
I assume this thread fixes it. Just going to try

The link above fixes this problem in apple connect perfectly .
