[2022] So do Odyssey delivery missions work?

I've done several missions now with my friend in multicrew Adder, and I have to say that I am not impressed with this game so far. Every ground mission invoving "We need to you obtain X item/data from Y outpost." has simply broken.

The mission giver does not recognize that we obtained the item requested. I don't even know if the mission progress is supposed to update when we get the item at the destination. Should it be "1/1 of X" when we get the item? If so, then it's just not recognizing when I have the item in my inventory.

Edit: It seems like sharing any mission with a team member makes that mission uncompletable, so I guess mission sharing is broken.
