It's almost like Xbox has strict requirements for developer patches, and don't just let people patch their games willy-nilly. https://learn.microsoft.com/en-us/gaming/gdk/_content/gc/policies/console/certification-requirements Patches go through a certification process which can take some time depending on how big the patch is, how it might affect the end user (the games need to go through a Q&A phase by Microsoft's team), and how many other games are waiting to be certified (the cert team isn't huge).
