I've recently bought a new phone so I've synced it to my Google account and installed all the apps I use. I've also done a factory reset on my old phone to wipe it.
However, now when I go to
https://security.google.com/settings/security/activity to remove the old phone from my list of devices there's no "Remove" button displayed when I expand the old phone's entry in the list.
There's a "Remove" button against the new phone and a message that the new phone might be suspicious activity with a link to secure my account. The help page - https://support.google.com/accounts/answer/3067630?p=devices&hl=en-GB&rd=1 - states that the way to get the "Remove" button is to follow the steps to "secure my account".
Now I know that there's no suspicious activity on my account so I don't need to change anything. So how can I tell Google that everything's OK and I'd quite like full access please.
