Cannot play any games on my Xbox series S

Xbox One games can be played on the Series S/X, but Series S/X games cannot be played on the One.

The One version of the game can be played on a Series S/X. The Series S/X version cannot be played on a One.

Also, I’m having the same issue playing my 360 games on my Series S, my Xbox Live account won’t download onto any 360 game on my Series S.

In this case, I would suggest you to perform a factory reset using the Xbox startup troubleshooter:

- Power off your console, and then unplug the power cord to ensure that the console is completely powered off. Wait 30 seconds, and then plug the power cord back in.

- Press and hold the Pair button (located on the left side of the console) and the Eject button (located on the front of the console), and then press the Xbox button on the console (the Xbox Series S and the Xbox One S All-Digital Edition do not have Eject buttons. Just hold only the Pair button nd then pressing the Xbox button).

- Continue holding the Pair and Eject buttons for 10-15 seconds. Listen for two “power-up” tones a couple of seconds apart. You can release the Pair and Eject buttons after the second power-up tone.

- The console should power up and take you directly to the Xbox Startup Troubleshooter. Select "Reset this Xbox" > Reset and keep games and apps.

See if this helps and please let me know.

Sorry for the delay, yes, I was logged in with my xbox profile but it was asking for my guest passkey. I got off the phone about an hour ago with a support representative stating he will call me back but never did. I got to the point to get to the factory reset screen but it keeps going back to the screen where it asks me to log in with my controller.
