What's with Ubisoft consistently failing on matchmaking in both Division games?

I just sat in game for 20 minutes while I tried three times to find a group for a main story mission, and nothing. Not one single, solitary person. I don't want to solo main story missions. Got no offers to join any other group, and no one joined mine. Really reminds me of the stupidity from Division 1. Lastly, if I DO manage to get into a group, if I join on someone else, then that mission only opens on the map for the group leader? What?

What is this Ubisoft?
