Unable to login on any device

So I’m unable to login in. Keep getting the “Closed - unable to log in to blizzard services” screen. I’ve updated, deleted, re-downloaded, re-updated etc on both my iPad and iPhone 11 and still keep getting the same message and just says to try again in a few minutes - it’s been about a week and still nothing works.
I’ve attempted downloading the game on my Mac as well but it won’t even let me do that.
Does this game still work? Did blizzard give it up? I don’t understand what’s happening?!

Getting this response during the 10 Year Hearthstone Event
