Xbox Accessories app stuck on 0% when trying to sync data on Windows 10

Yes. How it appears on screen:

We couldn't sync your data with the cloud just now



Try syncing again or use this app offline. (0)

*Try again* *use offline*

As long as you had a connection to Live when you were playing, your save will still be there. It will be saved in the Cloud.

When you run the game after re-installation, a window will pop up which will show you that the Xbox App for Windows 10 is syncing your save data. Everything will be as it was before.

Hi SquallLyonHeats,

Thanks for your post. I understand you are experiencing an issue when syncing your save data on Forza Horizon 4. To troubleshoot this issue, please try reinstalling your game. Here's how to do so:

Reinstalling Games on Windows 10.

I hope this helps.

Let's manually update the controllers on your Windows 10 PC through the Xbox Accessories app. To proceed, kindly download the "Xbox Accessories" app from the
Windows Store. This is a separate app from the Xbox app. The app will enable you to update your controller. Refer to How
to update your Xbox One Controller on Windows 10 for the steps.

Keep us posted with the results.

from my experience the windows 8/10 and windows phones 7/8/10 systems are not very well connected with the normal microsoft servers. on windows phone 7 there was an app called Xbox Extras that let you edit your avatar from the phone. looking on my WP10
there is a app called Xbox Avatars, which is most likely also available for WP8. i assume you just get the generic grey avatar showing? try installing this app and see if it syncs your data from the servers.
