We are an organization that previously had two Apple Team IDs. We requested Apple to update the Team ID associated with our apps. Out of our four apps, one app was using the Team ID XXXXX and the other three were using SSSSSSS. We requested Apple to update the app with Team ID XXXXX so that it would also use SSSSSSS. Apple completed this update, after which we refreshed the provisioning profiles and enabled Keychain Sharing.
