Defeated Illidan quests, Demon Hunter not unlocked

Posted this in New Player Tavern as I don’t think it’s a bug, must be missing what is required of me to earn Demon Hunter.

I completed the Prologue and Story mode and Demon Hunter is not available to play.

What am I missing?

All the other classes unlocked?

What happens when you create a Demon Hunter deck by clicking on the Demon Hunter portrait?
