Saved games on the Xbox Series S 512GB are stored on the console and, when you are signed in with your Microsoft account and online, copied to the cloud, which lets you carry them to another console or a PC. When progress does not sync, the cause is nearly always an account, a network or a game setting. Begin by checking that you are signed in with the same account on both devices, since a second profile on the same console holds different saves, and that the console is connected: open Settings, General, Network settings and run the connection test.
The checks in more detail
Cloud saves upload when the console is online and the game is closed or after a pause, and a game closed during an upload leaves the cloud copy stale. Xbox Support's pages on storage and games say that saves are tied to the account, not to the console. If the saves differ, the game asks which version to keep: choose the one with the longer play time, and be careful, as the other is overwritten. Some games, especially ones with their own server, such as online shooters and live-service titles, keep progress with the publisher's account, so check the in-game account link.
If a save is missing on the Series S with 512 GB, check whether the game is on the internal drive or an expansion card, and whether storage is full; a full drive can block saves. Clear the local saved games by choosing the game, Manage game and add-ons, Saved data, only after you have confirmed that the cloud copy is correct, as deleting the local copy then lets the cloud copy download. Restart the console, sign out and sign in again, and check Xbox service status for an outage.
If the saves still will not sync, contact the game's publisher and Xbox support with the game name and time. Check the console's date and time too, as a wrong clock can stop the console from authenticating with Xbox services and blocks syncing. Settings, General, Date and time lets you set it to automatic. Also confirm that the console is set as your home Xbox if you share an account, because a console that is not the home console still syncs saves but may restrict some features, and the home setting is found in Settings, General, Personalization, My home Xbox.
