Network Error. Can't use DLC items. Idk anymore

Got this game on the week of release, and since then I never got to play online because of this error. I have tried various fixes found on forums and sites but none work for me. I have messaged support that I am having this problem on PC and they sent me instructions on how to fix it for consoles, so no help there.
Is it just me experiencing this problem or are there others on here too? Seems like support hasn’t gotten enough of this kind of problem that’s why they’re not including it in their update of fixes. :frowning:
