Sims 3 redeem not showing up in EA app

I purchased the Sims 3 using CDKeys and redeemed it in the EA app, which worked and valid, but isn't showing up in the EA app library to download. It says in EA Help that I own the game, so the code isn't the issue, its the EA app itself. It's saying on the EA app to purchase the Sims 3 for '£29.99', but on EAHelp on my games that I own the game. I've cleared cache, reinstalled EA app, but nothing has worked to fix the issue. Any help would be appreciated :)
