I mainly play on Americas, but I also have a progress on Asia. I was able to play on Asia, but since I changed my account’s email, I can’t get pass the loading screen. I also face the same problem when I try to play on Europe. Americas works fine. I think I’m having the same problem as this guy in the forum below. The forum doesn’t have the solution, so I would like to get one. Thank you https://eu.battle.net/forums/en/hearthstone/topic/17617082874
