Symptoms:
How to control "Switching to Smart Interface" in a "Multiple administrator" environment?

Cause:
When multiple users are assigned with the "Administrator" permission profile, all of them would have the option to "Switch to Smart Interface" or "Opt-out of Smart Interface" for themselves and for all users. It becomes difficult for the main Administrator to control the same and could lead to undesired changes to Web Time Sheet.

Resolution:
Create a new permission for all additional administrators based on the the current administration permission profile but ensure that only the "Manage Account" permission is disabled. Assign this new permission to all the additional administrators. Only the Administrator with the "Manage Account" permission will be able to switch to Smart Interface.
