title: In which cases user.verificationStatus can be verified/unverified?
body: <p>I have created a project in google action with account-linking enable.
  and it is working fine on the test simulator and android device.
  But not working well with Google Nest Mini when I am trying to link my account to the project. And it is because of <strong>user.verificationStatus != VERIFIED</strong> same account used while on android and it was working.</p>
  <p>In easier terms :</p>
  <p>When testing with android device : <strong>user.verificationStatus == VERIFIED</strong> (with google account example@gmail.com). It means account is verified</p>
  <p>When testing with Google nest mini : <strong>user.verificationStatus != VERIFIED</strong> (with google account example@gmail.com). It means account is not verified.</p>
  <p>How the same account can have two verification status?</p>
  <p>Can anyone tell me in which circumstances <strong>user.verificationStatus</strong> verified or unverified?.</p>
  <p>Any information regarding <strong>user.verificationStatus</strong> would be good.</p>
