I'm experiencing the same issue. I have admin role with an access to certificates and profiles. I'm trying to add a new developer to a team.
I did check the "Access to Certificates, Identifiers & Profiles." checkbox.
The developer is able to see a team in AppStoreConnect but doesn't in Developer Center and Xcode.
Apple, are you going to fix this issue?
