Legion Companion App yesterday I tried to login today and it would only get as far as the character select screen.
Whenever I tried to select a character nothing happens. There is offline by each of the character names - obviously because I am at work.
I then realised it's patch 7.2 day and maybe the realms are offline, but Blizztards Realm Status Page says the realm is up. I can't actually log into the game at work to check if this is accurate!!!
According to this post it's not just me and Blizztards do know something is up. Bloody Typical!
