Battlenet Autenticator issue

[Deleted]

Hello there,
I have some issue with my battlenet autenticator. I keep autenticator app on my old phone, I use it rarely because I checked on mu account "keep me logged". Yesterday I loged out and to log in again it wants code from autenticator. The problem is that it isn`t working. I tried ro resync but I`m having note "sync unsuccessful" all the time. I`m stuck, can`t log in, can`t play. Help me please
