On a web browser, I can get all notifications. No problem right there. However, on the official Facebook apps on my galaxy s3, ipad and my sister's iphone, I am getting all but the "like" push notifications. I have tried creating a new fb account but I get the same problem. When I open the app though, I get to see all the "like" notifications, among others.
PS: this might seem so vain of me but it's just so annoying! :)
