Blizzard App Requiring Authentication

I used to use the Phone App Authenticator for WoW.

Recently, I've been seeing messages that the Wow Authenticator is going away and the Blizzard App will take its place. That's fine.

I've installed the Blizzard App and it worked fine for a few weeks.

Now I'm trying to log in to my account on the PC. It asks that I OK it on the Authenticator. I open my Blizzard App. The Blizzard App which IS SUPPOSED TO BE MY AUTHENTICATOR is ALSO asking me to log-in through Authenticator.

I went back to the app store to re-download WoW Authenticator. While trying to log-in, it's asking me for the code from my Authenticator...

What do I do now....?
