This app used to work alot better. The one touch authentication was convenient. However over the past few months it gets caught in a loop where it requests approval, only to clear the password and make you start again. This can happen several times in a row. I have opened tickets and filled bug reports, yet this still isn't fixed. Despite having account hacking issues in the past, the developer really doesn't seem concerned about fixing this.

Complete garbage app, didn't work on my old phone, still doesn't work on my new phone. I get the "Setting Up.." infinite loading screen problem for both. I've tried some solutions but nothing has worked. I get daily email notifications that someone is trying to steal my account, and I can't even get two factor authentication? What a complete joke.

App will not complete set up. Input email & password, hit set up button & app stalls at "Setting up..." for as long as I care to leave it running. Have tried all the permission & cache clearing, etc, recommended on Blizzard's website to no avail. Spoken to several CSRs, all very friendly, who go through the same support steps I've already tried. When those don't work, they consult a tech, whose response is "do a factory reset or buy a new phone". Thanks, techs. Galaxy S8+ running Android 9.
