Update expiration date mismatch between public doc and GDMF

Hello,

MDM protocol advices to use GDMF (https://gdmf.apple.com/v2/pmv) to manage properly updates ; the service defines which update is available for which device.

Nevertheless, we're seeing a difference between what GDMF returns and what is documented in the "public" documentation : https://support.apple.com/guide/deployment/manage-software-updates-depc4c80847a/web

For instance, for iOS 15.2, GDMF shows:

"ProductVersion":"15.2","PostingDate":"2021-12-13","ExpirationDate":"2022-04-12"

But public doc shows 11/02/2022 as expiration date.

Why this mismatch ? Which one is the right one ?

Thanks !
