Temporary Dialog Bug for Australian Testers
Blizzard blue post · Kaivax

We’ve fixed the bug that was causing this.
With the new build of the WoW Forever Beta, we have an unexpected bug where Australian players are being presented with a dialog when they log in telling them their social features are locked down. This is not the case, of course.
We’ll get the bug fixed as soon as possible.
