Uplay is an online digitally distributed software platform where video games can be downloaded and played with this tool. This service was developed by Ubisoft to provide a client-side user experience, just like others like Steam, Riot Games, Blizzard Launcher, Epic Games, etc. Therefore, if you play any of the Ubisoft games on your PC and every time, when you start the game, you will receive an error message regarding achievements. Then this guide is for you. Here we have shared the steps you can take to resolve the issue where Uplay is not syncing achievements.

According to affected players, every time they try to open a game in Uplay, a yellow notification will be displayed stating “Achievements could not be synced.” In this case, all achieved achievements may display correctly, but some of the recent achievements may not be easy to find because they are out of sync. So, if you also have a similar problem, check out some of the possible workarounds below.

Back up your achievements folder

Typically, Uplay uploads achievement files for all your games to the cloud.

However, this does not seem to be the case for all games, such as some Assassin’s Creed games.

For this reason, you will have to do it manually.

For testing purposes, you must first complete the game with some achievements.

Access your local storage of your achievements:

C: \ Users \% USER% \ AppData \ Local \ Ubisoft Game Launcher \ spool \% manynumbers%
After that, all you have to do is uninstall and reinstall Uplay and your game:
