Even after an administrator disables Salesforce Classic through the Lightning Experience Transition Assistant, some users may still see the option to switch to Salesforce Classic. This happens when certain user profile permissions allow access to Classic mode.
This article explains how to fully remove Salesforce Classic access for all users in your organization, and how to hide the option to switch to Classic for users with specific profiles or permission sets.
This article provides steps to disable Salesforce Classic access for your entire organization and to remove the Classic switcher for specific users.
Note: If you do not see the Lightning Experience Transition Assistant, the "Lightning only" permission has already been selected.
You cannot remove Salesforce Classic access for specific users if they have the View Setup and Configuration permission enabled through custom profiles or permission sets.
If your organization uses standard profiles, create a Permission Set with the "Hide Option to Switch to Salesforce Classic" permission enabled, and assign it to the relevant users.
Refer to Salesforce Help: Hide Option to Switch to Salesforce Classic for details.
