EA App Required Now?

I have noticed that some of the worlds I bought on the Sims3Store don't show up as owned on the EA app. They are installed and working, but when I scroll through the list of add-ons Dragon Valley Gold and Barnacle Bay show up as unowned. Monte Vista shows up, though. Since I did purchase them years ago this makes me wonder if it might be a problem in the future as I recently went back to Sims 3 and foresee playing it for some time.
