Help Please the new tenant unable to check in

I rented out the house and the doorbell device has been removed (no device shown in my Ring app) but the tenant unable to connect and I still received email: _We’ve recently blocked an attempt to set up your Ring device named **“xxx”** which is currently linked to your Ring account, _which i think this is the tenant trying to log in. I have followed the process as shown on how to remove device.Any suggestion without getting back again to the house. Thanks alot.
