Hello guys, i just lvl up a Hunkrow for Tailwind, but i tried it in game and i saw nothing changed about my speed

Tailwind is supposed to do that : doubles the Speed stat of the user and all other Pokémon in the user's party for three turns.

 

So can someone tell if if this skill is not working correctly yet ?

well it worked maybe lately when i pvping i found someone using hunkrow with tailwind and he os my gardevoir and salamence.:)

It was me eureka haha, but my speed didn't change i can tell you :)
