I am running into an issue where if I give a user access to additional extensions in UCP, they lose access to their primary extension. Is this expected behavior? I note that with groups, there is the option to add "User Primary Extension" to the list (included by default, I believe), but this option is not available when editing a user. It isn't terrible to work around it and explicitly add the user's extension to the list, but that also means that if the user's primary extension changes, the permissions don't automatically follow.
Am I missing something here? Is this a bug, or is it the expected behavior?
