I've been having pretty significant issues with Anthem since the VIP demo. I get the same errors on both my desktop and laptop which led me to believe that it was a network issue of some sort.
Here is what i've tried so far
I found a thread on reddit where people with a eero are having the exact same issues that i'm describing. All my other EA games work perfectly fine - Apex, Battlefield, Madden, etc...
I hope there is a fix soon, i've grinded to lvl30 despite these issues but they seem to be getting worse, making the game virtually unplayable.
