Update: Looks like this extension has been reversed for all certificates and certificates that were extended have now expired.
Marriott has extended free night certificates that were expiring on June 30, 2022 until December 31, 2022. No official announcement has been made, but you should see the new expiration date on your certificates. This is the fourth extension Marriott has done (1, 2, 3).
It also appears Marriott extended suite night awards, but this was a mistake and Marriott will be manually expiring these certificates.
