Why the change of how the pop up notification messages show up o my tv and how they work....

About this problem, I checked if all the updates are installed on the console, if not, do the procedure. Another solution is to check if pop-up notifications are enabled and configured : When you see a pop-up notification, press and hold the Xbox  button on the controller. If you miss the pop-up notification, press the Xbox  button to open the panel and select the Notifications block at the bottom of the panel to display it.

To change notification settings: press the Xbox button  to open the panel, then select Profile & System > Settings > Preferences > Notifications.

To change whether notification banners appear on the screen, select Notification Banners Enabled (or Disabled).

To change how Xbox notifications appear, select Xbox Notifications.

Check the Allow notifications checkbox to disable notifications or select on-screen choices based on how you'd like to receive notifications.

To change how app notifications appear, select App Notifications.

Check the Allow notifications checkbox to disable notifications or select on-screen choices based on how you'd like to receive notifications.

To change where notifications appear on the screen, select Default Notification Position.

Select one of six locations, indicated by a checkmark, where you want your notifications to appear on your screen. After making your selection, select Done.

To change how long notifications will be available or how long a notification will remain on the screen, select Notification time.

In the Show menu, you can choose to keep all notifications, even if they have expired and cannot be opened by selecting All items, even expired ones, or to show only recent items that can be opened by selecting Only items that I can open.

In the Pop-up time menu, you can change how long a notification should appear on the screen, choosing Standard or 15 seconds, 30 seconds, 1 minute or 5 minutes. Select the desired option and press the A  button to confirm.

Sincerely, Fernando.

Hey I love Pepsii! Check out the
Pop-Up Notifications page for more info and the
Xbox One preferences guide for changing notification settings. If your console was recently enrolled in the preview program these settings may have changed. Post back and let us know how that works!

I am having the exact same issue. The first few days I would get notification pop ups. Now I don't get them anymore. Everything is turned on but no notification at all. I am unable to find a solution. This is only one of MANY issues with this Xbox One
OS. But it is annoying that I don't know when my friends are logging in, when Party invites are sent to me, etc.

I completely agree with you. I'll get a notice on my phone that's reads "New Smart Glass Message" a solid minute before I get the notification on my Xbox One. Sometimes I never get the notification on the console. Plus reading and responding to a message
on the console, mid game, is TERRIBLE. I'm playing Ghosts last night, get a message, I hold down the button to retrieve said message and I get taken to the home screen where everything locked up for half minute.

When friends/peps send you messages on Xbox Live, Notifications aren't that laggy now.

But... the orange achievement notifications are quite laggy now compare those "achievement" notifications with how non-laggy the achievement notifications are on the Xbox 360, which pop up with practically no lag - smooth and fluid. That's how notifications
should work. This is probably a

"software" issue more than a "it's your internet".
