My WhatsApp notifications changed after update iOS 10

[iMore Question]

So,I receive a message from WhatsApp.When I didn't have iOS 10 I could see and answer without opening the app,just from my notification section.After update to iOS 10,I can't see the message ,just a notification 'Message from Marc' and I need to open the app so I can see what he wrote and then I can reply..
