Can't complete Shadowlands quest on second character

I recently bought Shadowlands and got through the first few storyline quests on a level 50 booster character. Then I wanted to play through it on my main. It gave me the option to start off on chapter 2 (Stranger in an Even Stranger Land) which put me on the platform outside Oribos. It tells me to speak to a guard so I do. It goes through the usual dialog and walks to where I need to turn the quest in, but the objective doesn’t complete and I can’t turn the quest in.

I’ve tried multiple times, I’ve tried talking to the npc I turn the quest in to, I’ve relogged, I’ve closed and opened the client, and I submitted a ticket in game to no avail. The same thing also happens on my wife’s character who is at the same progression level as me on her own boosted character

Do you use Azeroth Auto Pilot? According to Wowhead comments, you need to disable auto dialog for this quest to work.
