How come when

I linked my Xbox account onto my EA account onto my MacBook download the EA onto the MacBook yet the 46 added one have on xbox series s console isn’t showing up on my MacBook EA app isn’t that it’s supposed to do that what’s the point of linking my Xbox account onto it? So do I have to double buy all 46 items because that’s ridiculous and expensive should make one has all them for fans affordable just like one time have them all a bundle of everything who’s gonna sit there and spend a couple thousand dollars to get each add-on you guys add to the game don’t get me wrong love the sims grew up playing sims 2 and the Og sims castaway Sims busting out is always part of my childhood grown-up, but I don’t feel like paying double
