Hello,
I have been dealing with the same issue for more than a month as well. Changed my DNS settings, flushed dns, sent logs, I have a broken jpg on my home screen, which reminds me of a missing plug in. I can't purchase skins or battlepass. The game plays just fine but cant upgrade or get new skins. I have even reached out to the company i purchased my gaming computer from to see if they could help troubleshoot the problem. So far no remedy has been found. I will keep you posted when I find a fix. Best of luck!
