Snapchat app on the iPhone! Help?

I keep getting push notifications from snapchat that I have a new snapchat from some of my friends. Then snapchat will have a red bubble indicating 4 notifications. But when I open and refresh it, it shows nothing new. IPhone 5 here if that helps.

Tell me what to do?

Snap chat doesn't work very well with iPhone 5. I know someone who got the iPhone 5. She can see she got a snap chat through her notification, but when she opens the app and refreshes it, it doesn't show as if she's got a snap chat. But she can send snap chats which is odd.

Basic you need to look for a update from the app store for snap chat, because snap chat is not currently build for the iPhone 5 is what it is.
