This was the exact same wording on the Academy page "certificates do not expire, as they are tied to a specific Spark version.", all of a sudden, my old certificate (Which does not even mention expiry) was updated to show the expiry. All of this without so much communication as to the certificate was moved from the original space into a new 'credential' space.
All the people who added the certificate on LinkedIn before the 'Credential' movement still have older links that fail upon verification, at least that should have been constant.
A highly unprofessional transition for such a big company.
