Same set of issues since the weekend - the app will log in up until the character select and then once one is selected it throws you back to account login after a minute or two … until today (Sept 10), now it kicks back a battle.net error that says “unable to connect” from the initial login screen … so this was obviously not addressed during weekly maintenance
