Gamesharing not working properly

What you are doing is a violation of the code of conduct and not what the My Home Xbox feature was designed for. You could end up with Enforcement action for sharing account information.

If they're sharing account information, you're correct.

However, they don't put a restriction on which console you can designate as the Home Xbox, so if he isn't sharing account information, he isn't violating anything in the Code of Conduct.

Hi there! This is Ronnie, an independent adviser.

Nice to meet you and I hope you are having a great day!

I understand you need help on your Home sharing feature problem.

Have you tried checking on his subscription if it is still active?

If you are only able to play his games but not his subscription, his subscription may have been expired or suspended.

If that is not the case, try doing a reset and set up his account as home Xbox again.

refresh the console's system cache.

NOTE: This will remove the profiles on your console, make sure that you remember the email and password to your account.

No data or game saves will be lost doing this, everything is backed up to the cloud servers.

1. Press the Xbox button to open the guide.

2. Select Settings.

3. Select System.

4. Select Console info

5. Select Reset console.

6. Select Reset and keep my games & apps

This will also help sync the data on your console properly.

You need to remove the app and the wait for.the invite and then after that wait the months for the preview invite

In the meantime since he can't gameshare with you while.in the preview you both better off using gameshare properly and use it on your own consoles

I believe when it comes to destiny 2 gamesharing wont work as its linked to the account it first launches on

Gamesharing does work on Destiny 2. It's only the preorder bonuses that do not work with the gamesharing as they are for the person that preorders/bought the game.
