From what it seems, this isn’t the first time this has happened to people, I see threads dating as far back as 2019; I was in mercenaries last night, game froze so I shut down and went to bed. Now, almost 24 hours later when logging in I get a popup saying “You were disconnected from your last game. Reconnecting…” and the only option is to exit Hearthstone. Exiting the game does nothing, it goes back to this screen upon logging back in. Been this way for an hour now.
I’m thinking that since this has been known to Blizzard for at least 5 years there must certainly be a fix around now, so I’m hoping someone will post it. And no, the support article addressing this issue does nothing since it basically just say “wait”.
