I can log in to a browser without issue. When I try to log into the app, it says “We couldn’t verify your account with that information.”
I know the email and password are correct, as they are the same credentials that I use to log in on a browser. I changed the password, reinstalled, and had Blizzard “refresh” my account as troubleshooting led me to do, but it still didn’t work.
I have also tried using linked accounts (i.e. Nintendo, Apple, Steam) to login, but they all either fail within the built-in browser or I am still not logged in when I return to the main interface.
I believe there is something wrong with the built-in browser itself not communicating correctly with the API.
