System Admin is not able to view "List Views" created by another user profile.
|Knowledge Article Number||000231496|
|Description||System Admin is not able to view "List Views" created by a "Standard" user profile.
|Resolution||This Behaviour is working as expected.
List views created by standard user profile are Private and not Publically Shared views.
Any list view created will be private, if the user does not have "Manage Public List View" permission on profile then this list view will not be visible even to a system admin.
To make the List view public, users will need to have "Manage Public List View" permission assigned to the profile by a System Administrator.
