Remove users
If a resident moves out or no longer should have access to the charging site, follow these steps to remove the user:
Go to Invites on the left-hand menu and click the trash can icon on the row for the user to be removed.

If the user is also part of a user group (User Group), do the same there to remove them from the group.
The user must deactivate any active subscriptions themselves.
