I need to know the specific web domain that each of my downloads has been used for. Is there a way to get that information. I am needing to see if I need to obtain some additional licenses with some upcoming changes I am aware of with several domains I maintain.
Envato does not have a system for activating licenses or tracking which license is used/not used. This is done by the author of the item with their own licensing system.
In other words, contact the author of your item - they will be able to check the licenses for you, or may be able to give you a link to manage them all.
