You must manually refresh the data in the vSphere Web Client to see changes made to objects by other users during your session.
For performance reasons, the vSphere Web Client does not continuously refresh data on all objects in the inventory. All changes that you make during your current session are immediately reflected in the client user interface. Change made by other users or in other sessions are not reflected until you manually refresh the data.
The client view is updated. The date and time of the last refresh are displayed next to the refresh icon.
