My friend and I are trying to play the Apex Protocol missions together, but for some reason, I can't join or launch the missions, in neither COOP or singleplayer. It worked a couple of hours ago but now whenever I join I get stuck in the loading screen the green progress bar doesn't show up and eventually I get kicked off. And when I try and launch the mission I once again get stuck in the loading menu but if I press ESC it gets me stuck in the next mission, example, I'm loading into mission 1 and get stuck there but when I press ESC it starts "loading" for mission 2 but gets stuck, and then mission 3 and so on.
Thanks for any answers in advance!
