Q: iMessage full screen effects not working

Hi!

I got an iPhone 6s and just updated to iOS10

and most parts it works fine but I can't send iMessage fullscreen animation.

when i wright something in the text and use 3D touch to press the blue send buttom

to the right nothing appears, I know there is suppose to appear a menu, where

I can select in what way i want to send my iMessage, but absolutely nothing happens

no menu no nothing happens.

I tried the same thing with my iPad (4th gen) that don't have 3d touch and it works fine there.

and also, when i succeeded in sending for example ballons through my iPad to my

mothers Iphone SE with iOS10 she saw nothing only a message that I sent ballons to here.

I have tried to turn off iMessage and on again and also reset my iPhone via Itunes. still nothing.

is this an option only working on an Iphone plus model or iPads or have i missed some setting?

I would be very glad if someone could help me with this.
