Welcome back!
Very frustrating, I agree.
You should be getting the quest. I see another similar problem today:
and that player said it was resolved by getting the Heart of Azeroth. Your armoury is out of date, so I can’t see your character. Do you have the Heart, and are you all caught up on whatever Magni wants you to do today? I never heard of anyone not getting the Heart before max level, but maybe it’s easier to miss now with prepatch changes?
