iOS Hearthstone won’t recognize I’m logged in

iOS Hesrthstone doesn’t recognize that I have an account anymore. Since the last update, it acts like I don’t have a battle net account. It launches the mini-browser when I click log in & it lets me log in but as soon as I exit the mini-browser it goes back to acting like I did not just log in.

I’ve uninstalled & reinstalled multiple times. I’ve also installed Hearthstone on my PC to confirm my account works. It’s only the iOS app that doesn’t work.
