When I try to add a User to a Location, the type box only searches based on the User's assigned email. It does not actually search based on the name of the User. It should search for the name because names are easier to remember than emails. It also omits any User from the list of people that can be added to a location if the User does not have an assigned email address, an issue as in the old PBX emails were optional, so not every User has an email address.
