Game Sync Issues

Can you see if there is any update for the game available in the Windows 10 store? If the game version is not in sync with the latest, it might be causing issues with the sync from the cloud.

And are you syncing a save from a console version, or a different PC, or is this an issue with uploading your local save to the cloud? Curious if we're troubleshooting actually transferring saves to different devices, or a general sync issue.

I have been having this exact issue for a few days. All troubleshooting steps fail. Syncing 20MB for Rise of Tomb Raider fails at 40-50%% after 15 minutes. The message is "We could not sync your data. Please try again later or player offline." Error code
is blank (). For some unexplained reason though, I found that connecting via my phone's hotspot works - and I synced ~1.5GB of Fallout 4 data in 30 minutes. It's lucky I have this temporary work-around or I would have been stuck.

All other Xbox network functions, game updates and downloads, work without any issues with my normal Centurylink DSL connection. Network and multiplayer tests pass with flying colors. it's just the cloud data syncing that's failing.

For all that is holy, how is this issue not fixed yet, I am trying to sync Halo MCC and on the 15th try still no luck

Before anyone tries to give me the troubleshooting steps, this has been happening as far back as I can remember

Same issue, but different consoles, have had two different ISP's, multiple modem/router configurations, hard resets, profile deletions

God knows how many games this has happened in since I got my 1 TB xbox back in November, the games with the smaller save files usually do it in two tries which is alright, but the bigger save files

I know my profile has a massive amount of data, but I have never had an issue with cloud syncs on xbox 360

And don't even get me started on achievements, constantly not getting any notifications, a quantum break one says 100% but still hasn't popped since the day the game came out so there goes a 100% completion

For all the good the cloud does, why is so much broken

It just feels like there is a tier of servers, where downloads, party, online gaming is tier 1, and then cloud saves and achievements are on the last possible tier lol I can easily download 12 GB in an hour but its taking ages to download possibly 100 mb(probably
not even) of save data

Just to let people know: none of the troubleshooting steps worked, not even power cycling my modem. After 10 days trying everything without being able to play my games I tried one last step: factory reset my Xbox One and re-download 1TB+ of games expecting
this would do.

Well, it did not. Same issue on new installed games. So I just accepted the fate that I have lost ALL my progress.

Even to get things working again was a PAIN: had to manually delete local/cloud game saves. After that I could finally play the games again (from the scratch obviously).

So thank you MS!

I have already tried that. Twice. Manually deleting my account and using the reset but keep my apps and games on my xbox.
