Hi there,
I currently hold an Apple Developer account that has two teams associated with it. One is my personal team, for which I pay for the Apple Developer Program. The other is a corporate account for which I am working. Despite seeing both teams in the Apple Developer (web) portal, I am only able to see one of them in the Xcode account settings page.
I have reached out to Apple Developer support over the phone, and have been advised to post this issue here to better access support.
