I just installed Bluestacks 2 for the first time ever. Pretty cool software! However, I waited for over 45 minutes for the “Signing In…” dialog to finish before finally hitting cancel. I figured I might have typed the wrong password. That’s exactly what happened. It seems that it just keep retrying the same account information until it succeeds and don’t let the user know the password entered was incorrect.
If you get stuck on this screen, hit cancel, make sure you type the correct password and try again. It shouldn’t take very long. When I fixed my password it took about 7 seconds!
Hopefully this helps someone.
