We had created an app for a client within our own account. And I had pushed 2 builds for it. It was approved and made live. But the client wanted that app to be transferred to their account so we did that. I asked them to add my account to the team so that I should still be able to push an update for the app. Now when I archive the app and choose on Distribute option, it says to create an app record which won't be possible because the app with the same bundle id exists. How do I push an update to the exisiting app from my own account? What do I need to do in this case? Do I need special distribution certificates, provisioning profiles, etc? Do I have to switch teams in my XCODE?
