E/zzf: Problem retrieving SafetyNet Token: 7: Android

I have this error:

E/zzf: Problem retrieving SafetyNet Token: 7: 

I am working on AndroidStudio with kotlin, the main problem is there is a captcha coming on everytime a I try to login via firebase phone auth.

Things done:

1. Added all keys in the firebase project (SHA-1, SHA-256 -- both debug and release)
2. Enabled Android Device Verification

And when implementation androidx.browser:browser:1.2.0 is removed, the following error shows up.

java.lang.NoClassDefFoundError: Failed resolution of: Landroidx/browser/customtabs/CustomTabsIntent$Builder;

I concluded, if E/zzf: Problem retrieving SafetyNet Token: 7: error is solved, all the other errors will be solved automatically.
