I can't activate smart lock

[BlackZeppelin]

Hi all. I wanted to activate smart lock at home when connected to my wifi I am totally confused about the message when I attempt to activate it.

So when I press on smart lock it says, as per my 2nd screenshot, the action is not allowed. When I click on the details, it has something to do, as per my 1st screenshot, with the default email which I don't understand at all.

I deactivated device admin for the default email app but I still can't activate smart lock. As you can see, there is a prompt to uninstall the email app.

Does anyone understand this? I have no idea what the email app has gotten to do with smart lock.

Sorry, now it's activated. I don't know how. A few hours after I deactivated this email as a device admin. I have no idea what difference this made but there you go.
