I use the same email address both in xCode and at developer.apple.com. I have only one team (individual) in xCode, and it uses that particular email.
If I look at the Signing Certificate at Signing and Capabilities at Xcode, there is a 10-digit identifier after it, lets call it QWERTYUIOP.
When I then go to the developer.apple.com, and log in with the same email address I use in xCode, my Team ID is different than in xCode, lets call it ASDFGHJKLX. The same identifier can be found at Certificates, Identifiers & Profiles.
When I developed an Xcode app and tried to get it processed in developer.apple.com, no bundle IDs were found.
If I look at my Keychain Access I have certificates with both IDs available. My Developer Certificates are from xCode (QWERTYUIOP) and my distribution certificates are from developer.apple.com (ASDFGHJKLX). I've deleted and re-created them several times but that's what happens.
Can anybody help? Support has not been responsive yet.
