Which Server are you on? And which platform (PC? PlayStation? Xbox? Switch?) I don't remember going into the Marketplace tonight on US PC & PS Server, but I can go check it out right now. EDIT: It's loading for me on US PC.
marketplace is still down because of the atlantean bundle glitch that occurred the other day that the devs don't want to discuss because it makes it seem like more bad faith stuff happened and won't be properly responded to, even though supposedly "there are consequences". if consequences had ever mattered before, there would be no 5 billion cash items not but here we are. and that's why you can't use the marketplace.
But since that happened, it's been turned back "on" for US PC. I've been able to add Daybreak Cash and purchase supplies I needed. And it's loading for me tonight.
I think the MP is only down for PS. They probably have to work with Sony to fix the error on our side. Edit: It's up for PS.
