I recently was added to an Apple Developer Team by a customer for uploading their app to the app store. And I can change my team on the appstoreconnect website but on Xcode and developer.apple website I can't see the new team. I just can see personal team and the team of the company that I'm working for. I also did the instruction in here https://developer.apple.com/forums/thread/675816 but not worked in my case.
