Just gun whip Amari in the face and then put the weapon away. I had the same problem too and the solution worked for me.
No problem.
I'm assuming of course that what you meant by the dialogue with Amari not triggering is because it says this individual is busy when you try to talk to her, right?
Well I meleed her with a submachinegun. Sorry I don't think this solution will work for you then. I think the fact that I hit her as soon as I figured out there was something wrong with the quest where as you did a lot of other things before coming back might also have an impact as well
Also on PC here so I guess we might have different glitches lol.
