The ‘Update Smart View’ form will appear where you can edit the individual settings for the Smart View. Click the ‘Save’ button at the bottom to save any changes made.
To remove the Smart View entirely, click the red ‘Delete’ button located at the bottom of the form. A prompt will appear requesting for you to confirm your intention to delete this Smart View. Click the ‘Delete’ button to complete this action.
