I currently have my own individual App Store Connect and Apple Developer distributor account registered with the email address m*******@*mail.com. For one of my clients, we also created a separate individual App Store Connect and Apple Developer account. I added my account as an Admin to the client’s account. On the App Store Connect side, I can perform all operations without any issues, such as managing the app, handling TestFlight, and submitting new versions. However, when I access the Apple Developer portal, I cannot see or manage the accounts I am responsible for. For example, I cannot view information such as the Team ID, certificates, provisioning profiles, or other developer settings. To work around this issue, I created a new Apple Developer membership using a different email address. However, when I logged in with that account, I was still unable to view the Team ID or other developer-related settings. My question is: Has the system always worked this way, where App Store Connect and Apple Developer access are managed separately? Or could this be an unnoticed authorization or configuration issue? I would appreciate your clarification on this matter.
