Samsung UE55 integration

Hello,

I have just installed and setup HA. I added my Samsung 55 TV after automatically being discovered by HA. I can see the state but I can not control it. I know I should see a pop up on the TV to allow being controlled by HA but no pop up appears. I have removed and added 2 times but without success…
I can control TV with Samsung app through phone without any problem.

Any ideas?
