Microsoft has acknowledged that their update broke something in games (and in many other things, the list of known issues is extensive). They should fix all of that. Because it’s them who broke it.

Sure, Blizzard could do the same thing, but they could also do nothing and wait for Microsoft to fix the problem and for now… That’s what seems to be happening
