FAQs
Can I see what assets a user has downloaded from a portal?
You can see which assets have been downloaded from a portal, but you won't be able to see who downloaded it. This is because portals are for non-logged in users, so by virtue of how that works, we don't collect the necessary data to show that. You can find more information in our dedicated article on portal analytics.
