I recently upgraded to Windows 10 and I discovered that there's a Notification Center. In short, I enabled Facebook push notification and I receive them properly with no problem, but when I open the Notification Center and click on the notification that I received, it does nothing, it doesn't open the link, and the notification goes away.
After a Windows update, I encountered a similar issue. Apparently, parts of the Notification system now run as a Background app, and this can be set in the Privacy Control Panel (CPL).
- Press Windows and select the Privacy CPL.
- Scroll down to Background apps
Let apps run in the background.
- If Facebook or your preferred browser appear in the list of apps, enable them. [Edge is off on my settings because it is not the [preferred browser.]
Windows Security, particularly if you use Defender.
Also, third-party privacy tools such as O&O ShutUp10, shown below, can also disable background apps. Allow App Notifications.
Hopefully, Notifications will work again. Post here if it works, or you found another solution.
