"Unable to synch data with cloud" error with Microsoft game pass for PC

I found the solution after 1 day and a half ...

The issue comes from the xbox game bar application parameter ; the
account need to be connected. This is absolutly not intuitive because I was already connected in the XBOX application.

All these account conexions are not user friendly

All of the data should be synched to the cloud. Have you tried rebooting?

HI again,

For the game progress problem you might try these guides:

http://support.xbox.com/en-US/games/troubleshooting/cloud-storage-sync-error-messages

http://support.xbox.com/en-US/games/game-setup/cloud-game-saves-faq

the progress should be saved when you are connected to Xbox live.

You can also try and delete your save data on the drive and then synch your data from the cloud. If you want to delete all data select delete everywhere and it will delete the save data from the hard drive and the cloud.

Hope that helps.

The simple answer is to sign out and resign in. That is typically the issue. Here's a link to cloud data. That said it could very well be a common server issue:

"Xbox Game Pass for PC] Just lost my saves"

"Syncing Xbox One game saves to the cloud error messages"

I wonder about this too.[/quote]It's cached locally on your console and then synched to the cloud. Once the synch is complete it will be on the Cloud only.
