Problem with facebook notifications?

[NMVA]

Hello, I've been having problems with fb notifications, I posted a picture to a friend's timeline... She commented on the picture but I didn't get the notification, I had to go to the picture and read the comment... I didn't get it on my iphone, nor my laptop... I went to settings and I previously selected to send me all notifications, but I don't get it, any help? Is someone going through the same?

Ya . Sm times not shown on the spot. You edit notification settings

DEactivate and then again reactivate your account after 1 hour or so..This will give a bit refresh type of thing to your account..!!

Don't sometime it happens in Facebook. If you want all notification of that friend then you have to add him in best friend list.

I think you are turnoff your notification option in Iphone. So turnon you will get notification.
