The ‘seen’ button has been created to give users the option to mark an artwork as seen on the spot.
Using the button as a ‘collection’ button is a different approach, especially when you want to use it retro active. But this works contra intutive if you use the button for an artwork you have seen years ago. The art may have been gone already, so the ‘seen’ button should not work if the artwork is removed.
Linear ticket has been created (SAC-1533: deactivate ‘seen’ button for archived artworks.)
