Issue Description:
This document provides instructions for deleting Licenses for apps that are installed in the printer.
This is particularly useful if there were duplicate Licenses installed in the printer and one needs to be deleted to make the app work.

Solution:

Access the printer's embedded web server (EWS), then click on Apps.

Select which application needs the License to be deleted. The example here uses Fax over IP (FOIP).

Click on the drop-down for the selected app and click on view license.

Locate the app License that requires deletion and click Uninstall.
