Is it possible to add last_ip to the deny list?

Hi there!

We are trying to limit the amount of user data we store in the Auth0 Database. We have reviewed the docs and this FAQ around using the connections endpoint to add profile fields to the deny list, but are not having success:

The /api/v2/connections/{id} PATCH has a status 200 and if we call /api/v2/connections/, we can see last_ip listed in the non_persistent_attrs, however we still see the last_ip address listed under the user details in the dashboard.

We preformed the steps outlined in this FAQ:

We have also confirmed the Management API is scoped for read:connections and update:connections

Is it possible to not persist the last IP?
If so, are we missing a step?
