Facebook Chat for IPhone no alerts, sounds or vibration!?! HELP!?

Before the newest upgrade for the Facebook app on iPhone it would ding when someone messaged me through chat, now it doesn't do anything! I know they integrated the chat in with the 'email/message' portion of the app so I think technically if you don't get them they go to your messages, but neither happens! It doesnt make a noise or send an alert or put the message into my message folder. I open my facebook on my laptop and Ive missed DAYS worth of messages I never knew about :(
