Hello, I have a question regarding push services after app transfer completion and hope you can clarify it for me:

If the original team does not actively disable existing APNs and JWT connections as well as push services, will the old P12 certificates and P8 keys remain valid for a short while so users can still receive push notifications? If yes, the new company only needs to finish certificate updates shortly after receiving the transfer success notice. How many hours is this grace period normally?
Whether the original team shuts down APNs and JWT services or not, will the old P12 certificates and P8 keys become invalid right away, leaving users unable to receive pushes until the new company updates the relevant credentials?

Thanks for your support and looking forward to your reply.

1. Both the P12 and the P8 based JWTs will remain valid:

For a trivial but non-zero time after the transfer is complete.
if the old team has already open connections to APNs at the time the transfer is completed, they will be able to continue sending notifications until the close the connections and try to reopen them, in which case their authentication will fail

2. Whether the original team shuts down APNs and JWT services or not, will the old P12 certificates and P8 keys become invalid right away, leaving users unable to receive pushes until the new company updates the relevant credentials?

Th old certificates will become invalid almost right away, after a trivial but non-zero time has passed. Once the connections are closed the old certificates will no longer work, and the new team has to start using their own credentials.
