I upgraded to Windows 10 when it launched, then did a clean install. Notifications have never worked properly for me and I can't figure out why, other than it being an issue with the OS itself that is still not fixed. I've tried 2 further clean installs, but this has not fixed the issue.

The only modern app I use is the Xbox app. I have it set to deliver certain notifications and all of the settings in Windows itself are correct, plus the app is allowed to run in the background. However, sometimes I get notifications and sometimes I don't. I'd say about 40% of the time I don't, so often I launch the app and find I have new messages from friends, or new comments/likes on my activity feed, but I did not receive any notifications about this.

Anyone got any idea what the issue might be? Anyone else having the same problem with the Xbox app, or notifications in general?

Thanks!
