Java Question (Solved) cannot find symbol PhoneAuthCredential

Hi all

I tried to add phone authentication to firebase auth library but I could not find PhoneAuthCredential class in firebase-auth-10.2.6.aar .

Am I missing something or doing it wrong ?

I found it.
I needed 11.0.0 .
For some reason my latest version of auth and many firebase and google play services was 10.2.6 .
