I can’t enter the game on iPad since the last patch

[kingdomdude-1606]

Game stuck on "Hearthstone" loading screen (iPad)

Workaround… Change your battlenet pwd via the Battle.net website. This will force a login screen on the Hearthstone app again, login with new pwd. Play until you are ready to stop BUT before you quit playing, logout of your HS account (bottom right/switch account) then quit the Game. Next start you will be promted for your login credentials, Login and play, then logout when done, login/logout until a fix is released.

Posted the workaround I am using here.
