Notification of Xbox achievements on Windows 10 not appearing while gaming

I find hearing those sounds cute and don't want anything changed about it.

Achievement notifications are fine, but those big fat Windows 8 styled boxed notifications ALWAYS appear on the bottom centre of the screen.

Xbox 360's notification system is SMARTER because it appears either on the top centre, top left, top right, bottom right or bottom left of the screen especially in while playing games. The Xbox 360's Dashboard's algorithms are smart enough to make the notification
bubble appear on your screen where it less likely interfers with the game. With Xbox 1, you just get a big fat notification box which always comes up in the bottom centre of the screen.

I do like it how you can customize the colour of achievement notifications on Xbox 1, mine's orange.

Thanks for the extra info

Try using your account everywhere (including the Microsoft store) to see if the achievement notification appears

And this can be a bit dumb, but make sure to have notifications enabled for the Xbox game bar via windows settings and game bar settings

Hi there! This is Virginia O.

I understand that you are experiencing issues with your achievement notifications not popping up.

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

Please check Xbox notifications settings make sure notifications are enabled by going to Settings > Preferences > Notifications. Ensure "Achievement notifications" are turned on.

And then hold the power button on your console for 10 seconds until it fully shuts down. Unplug the console for 1-2 minutes. Restart and check if the notifications appear.

Next is to sign out of your Xbox account and signing back in because account sync issues can cause notifications to not display properly.

Then check your Internet connection because achievements sync through Xbox Live. If your internet connection is unstable, it prevent notifications from appearing.

If the issue persist after performing the troubleshooting steps, kindly see if achievements pop up in another game. If they do, the issue might be specific to the game you're playing.

Thank you for your cooperation.

Windows 10 It appears while I try to launch the game

Here is the support article that talks about playing Windows 10 games offline: https://support.xbox.com/en-US/games/game-setup/play-games-offline-windows-10

According to the article, achievements will be saved and applied the next time you sign in online again (but you won’t see the achievement notification, or “toast”).

Personally, I find it best to stay online if you plan on completing those serious achievements. As far as I’ve seen (with offline Xboxes), offline achievements may not always be tracked reliably.
