Notifications

What is it that isn't working? Do they simply not show up in the notifications menu? Could you have unintentionally turned notifications off in the Settings app? If that's the case you can find a tutourial on how to turn them back on here.

If that doesn't work, you'd need to add some additional information on the issue, for me to be able to assist you further.

Delete all focus settings then you can create them later , notifications get in and turn on summary don’t anything just turn it on then in notifications get there and turn it off/on and select immediate delivery, do that in every app in notifications
