Notification of friends online on the xbox how to remove this?

To change your notification settings, press the Xbox button
to open the guide, and then select System >
Settings > Preferences >
Notifications. You can choose what to do with individual Xbox and app notifications (or turn all notifications off), adjust the duration of pop-up notifications, and more.

This is normally down to using the favourite feature on a friends profile. Open the guide, go to "people" tab and open your friends list. Select the profile of the gamer you want to stop the notification for and open it, select "change friendship" and either
change to just friend from favourite or remove.

You can also go into settings>preferences>notifications>Xbox notifications>friends & broadcasts and change what you want to have notified there.

How about an option to only get online notifications for friends that are favourites?

But that stops them from seeing you are online at all. How do you stop sending notifications that you are online but still let them see you are by going to their friends tab. It’s the notifications are the privacy problem.

@ U gO, I might try this next time I'm on my Xbox 1 console (it's 1 am for me).

It would be great if it works like friend notifications on the 360 (eg. you sign into Xbox, Xbox tells you how many friends are using their Xbox 360/Xbox 1 console online). I'm not really into categorizing my friends. But for Xbox 1, I've already favourite'd
my favourite friends just so that I can get a notification when they come online.
