Update: And yes, Leelavati completed the Elsweyr preview. (Happened to see the post down below after I had posted this one.)
My nightblade Leelavati has not been given the quest The Tharn Speaks by the prophet. She has visited the prophet in the harborage and he tells her that he and Tharn have much to talk about. Leela has visited wayshrines in several zones, done other quests, and everything else she can think of to advance the main quest line but she's out of ideas. And she is level 30 although that is not supposed to matter since One Tamriel.
I did a search and found out that this has been a problem for other players as well - dating back to 2014! (Really?)

Hopefully the daedra and tech support will take notice and give me a helping hand here. I also submitted a ticket but they replied to check the forums.
