[2020] Assignments not working?

So, my husband and I really just got into this game and after the first assignment was done, he was no longer able to select assignments at the assignment board. We didn’t realize this until after we completed the second assignment and the miners trade unlocked for me but not him. Is this happening to anyone else? Tried reinstalling the game and everything, nothing changes it. His first assignment doesn’t disappear and no missions appear on the map for him unless I select one. Any idea how to fix this?
