Re: why doesnt the app show all my add on downloads

i purchased an add on for my sims 4 game, and when i got on my computer it said the app needed to be updated and restarted so i did that, and when i logged back in my sims 4 and add on pack was gone. i was able to get my sims 4 back being that i already purchased it, however i was not able to get my add on back and i have purchased that as well. How do i get my add-on back?
