With the Spring'21 release, Salesforce have added an In-App Learning icon to the global header.
Is there a way to remove this from the header?
Unfortunately, you cannot remove In-App Learning icon. All users will have access to view the new icon in the global header and the panel. Check more details here.
Thanks
Currently there is no way to remove the icon, but there is an active idea to allow it to be hidden.
