DK order hall issue

I stopped getting new order hall quests after starting Shadowlands and now that I’m 60 I don’t really know what to do to go back and finish them. The last quest I did was turning in “Advancing the War Effort” after doing world quests for my covenant. I’d like to go back and get the rest of my class set for transmog so any help would be appreciated.

First, make sure you have trivial quest tracking turned on to make sure you actually see available quests. (It’s one of the options from the magnifying glass on the minimap.)

It’s a been a while since I’ve done the DK campaign, but I don’t remember any particular sticking points on that one. Looking at the wowhead guide, it looks like the next steps involved completing some stuff from the mission board and getting 5 Bloods of Sargaras.
