BUG : On IOS after installing Norton 360, the Norton asks 2 twice for password

After downloading Norton 360 software via Apple Store. Norton asks us to sign in. It requires 3 pieces of information

User code
Password
Verification if we are human

The problem is that once this validation is complete, it still asks us AGAIN for the password.

To whom at Norton can we send that there is a bug with Norton 360 under IOS?

To confirm. It is the 360 app you are activating and not the Norton Password Manager, NPM, app.  NPM would require the vault password after signing into your Norton Accout.
