Thank you for your reply. Could I understand it this way? After the App transfer is completed, if the original team does not actively shut down the existing APNs and JWT connections and push services, the old P12 certificates and JWT tokens generated by the old P8 keys can still work normally for a short period of time, users can receive push notifications without immediate invalidation. The new company only needs to gradually deploy and replace them with its own new push credentials after receiving the transfer success notification. If so, how many hours does this grace period usually last? Besides, will both the original company account and the new company account receive relevant emails after the transfer is successfully done? Thanks a lot for your assistance, waiting for your reply.
