Weird problem thats happened a couple times lately. I get disconnected and if I try to login using the WOW login screen it asks for an authenticator code. When I check my authenticator (phone app) there are no game requests and subsequently no codes.
If I shut down WoW and just relaunch the game from the battle.net app (which has been running happily the whole time btw) it goes straight into the game.
So, why am I needing an authenticator code in WoW itself? And why is the phone app not showing any game requests?
