No worries, it's the setting for Xbox Series S as well. By the way, what is the exact error or issue that your son is getting whenever he is trying to play or sign in on Xbox Series S?

Hello, I hope you are well.

Please check these steps.

Yes, it is possible to download your Xbox 360 profile on your Xbox Series S. The Xbox Series S supports Xbox 360 games through an emulator. However, there may be connection or authentication issues that need to be resolved.

How to download your Xbox 360 profile on your Xbox Series S:

1. Sign in:

Make sure you are signed in to your Microsoft account on your Xbox Series S with your Xbox 360 profile.

2. Download your games:

Once you are in your Xbox 360 game, you may need to download your Xbox 360 profile if it is not already on your console.

3. Troubleshoot connection issues:

If you are having connection or authentication issues, try the following solutions:

Check your network connection.

Restart your console.

Sign out and sign back in to your Microsoft account.

Verify your Microsoft account security information.

Reset your Microsoft account password

Hello Rhmd, to do this, you need to set the Series S as the home Xbox, then make sure both your account with the games on the Series X, and his account are both signed in on the Series S. Once you do that he will have access to all of the games on the
Series X from his Series S.

3. ONLY the Xbox-Series X has this issue, No other, including the Series S which is the “little brother” of the Series X

4. The issue is the Series X

Are you sure, that the Series S is not affected?

Okay so just to make sure I understand.....

I make my sons Series S (MY) Home Console.....

He can play Online with me if I am on my PC signed in as me.
I can also sign into my own Series X and play my games.

We wont be playing together on XBOX on both Series S and Series X.
