I have been tasked to update an existing app. I'm now at the point where I would like to update to a newer version.
My previous process was to:
- Select my Developer Account
- Use "Manage Signing by XCode"
- Archive
- Upload bundle
But now I fail at 3).
The app owner has added my account within App Store Connect and made me Administrator. But when I try to upload it via XCode it tells me that the bundle id is already taken.
How do I proceed? Where do I find information on how to maintain an existing app for a different developer account?
