In-game sign-in needs to go. It's janky and hardly necessary. Same for in-app permissions.

Additionally, you may need to check the permissions for the D drive to ensure that the Xbox app has the necessary permissions to save games to it. To do this, follow these steps:

1. Right-click on the D drive and select Properties.
   
2. Click on the Security tab.
   
3. Click on Edit.
   
4. Select the Xbox app from the list of users and groups.
   
5. Make sure that the Xbox app has the necessary permissions (e.g., "Modify" or "Full control").
   

If the Xbox app still doesn't have the necessary permissions, you may need to contact your system administrator or the person who set up the permissions on the D drive.

having same issue this Pc App is JANKy

Hi there! This is Virginia O.

I understand that you are experiencing issues signing into the Xbox App on your Samsung tablet.

I apologize for the inconvenienced this has caused you. I will do my best to help you.

Please sign In on a browser first. Open a browser on your tablet and sign in to your Microsoft account at account.microsoft.com.

And then clear cache and data. To do this please go to your tablet's Settings > Apps > Xbox App.

Tap Storage, then select Clear Cache and Clear Data.

Restart the app and try signing in again.

Next is to uninstall the app from your tablet.

Restart your device, then reinstall the app from the Google Play Store.

Then check permissions. Your Xbox app should have the necessary permissions. Go to Settings > Apps > Xbox App > Permissions, and enable all required permissions.

After that is to update your device and app. Kindly ensure that your Samsung tablet's software and the Xbox app are updated to the latest versions.

Thank you for your cooperation.

Hi, doesn't work in the same way.

On PC it's a bit more different.

For this you need to sign in with your Microsoft account on both Microsoft store and Xbox app.

Make sure to enable offline permissions inside Microsoft store > settings

After that you need to download first the desired games with your account using the Xbox PC app and the you can sign out and sign in with your brother's account.

(But this doesn't work for all games)

I found this on a microsoft page:

1. Press the Xbox button on your controller to open the guide, then go to System > Settings > Account > Privacy & online safety > App privacy.
   
2. Give permission by selecting the check boxes next to your apps.
   

If you’re signed in with a child account, you’ll need an adult to sign in and give permission for apps to access your data.

Hope this helps.
