I have several 500v2 control units on 9.1.4 connected to each other via SCN over websocket. It is not SE. When I add users to a hunt group, if the user is local to that control unit, it keeps the change. If I add a remote user from any of the other control units, as soon as I press ok, it removes the remote users from the group. It happens no matter which IPO the group is configured on. Any idea what might cause this?
