Fix Discord Notifications Not Working in Windows 10
Discord notification issues are rare, but when they do occur, you miss out on some important activity happening on the platform. If you’re in a similar situation where you’re not getting timely Discord notifications, there are a few things you can try to fix the issue.
You can try changing your Discord status, disabling the feature on your PC that blocks all notifications, and even reinstalling the Discord client. Here are all the ways you can make the app deliver notifications to your computer on time.
Discord offers multiple user statuses so you can tell people what you’re up to. One of them is Do Not Disturb, which blocks all of your desktop notifications. You should make sure you’re not using this status, and if you are, change it to Online to resume your app notifications.
