due to some change I changed my mobile device. I used to had Authenticator App on my old mobile device, but dont have it anymore, cant install again and configure.
Currently this computer device is the only that has access to battle.net app and battle.net website.
Can you tell/help me to remove authenticator form my account and allow me to configure this again on my new mobile device?
I opened a ticket on Poland but its already 3 days and I received no information.
