After an app is transferred, its associated App ID is also transferred to the recipient’s account at developer.apple.com. If the transferor’s App ID was a wildcard App ID, it’s converted to an explicit App ID that exactly matches the app’s bundle ID. Associated client SSL certificates for push notifications aren’t transferred. If the app uses Apple Push Notifications service (APNs), the recipient needs to create a client SSL certificate using the recipient’s account at developer.apple.com to reenable it.
