Thank you for the response. but rather that something has gone wrong >>after you’ve created them Yes, the problem is after the create which is out of my control, but now I'm stuck... Xcode always gives an error when managing my account certificates. This is under Signing certificates for "My Name": Clicking the "+" sign gives the error "There is a problem with the request entity. You already a Development certifiate or a pending request." Xcode always gives an error when managing my Team Developer ID Installer Certificate. Under Accounts, highlighting my email, clicking Manage Certificates>Developer ID Installer gives that above same error. Logging into my Apple Developer account, I am unable to revoke existing Developer ID Installer Certificates.
