Thx in advance hopefully this isn't out of sub rules but is kind of game related!

Took a break from the game for a couple Months and went to re-install the game on battlenet which I have still downloaded. I guess the Problem lies maybe on my Phone? Im not sure.

I go to battlenet on PC and Phone both of which need authenticator verification. Okay open authenticator which will not go past the screen saying " this app will be merging with battlenet app on this date" etc etc. So I cant use the authenticator.

Go to recovery but sms option has an old phone number on file. Again apologies if wrong sub but wondering if anyone else here had an answer?
