Notifications not appearing until 1-2 minutes later

I always get the achievements but they never inform me with a notification sound. Anyone know how this is happening? But yeah, sometimes the points show up 1 or 2 weeks later. Still no notification. Help appreciated...

It's also worth noting that the "connection issue" notification takes about 5 minutes to appear.

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.

Never mind the issue resolved itself.

The missed message eventually appeared in my notification tab, though it took over 30 minutes to do so.

Suggestion:

Missed messages should appear in the notification tab *immediately*, not at some indeterminate future point in time.

I've been having problems with notifications since later November. Party/Game invites appear on my screen but don't appear in the Notifications area - so I can't accept them. I've checked all the settings and notifications are supposed to be on. (And
I was getting them before the update). Reset everything ... but nothing works. Not sure what more to do ...
