Re: can't download or access previously owned content

@aauurii01  Okay, then it's possible you don't have the game installed through Epic at all, just the ability to launch your EA App install through Epic.

Under Add-ons in your screenshot, do you have the option to download your missing packs, or do they already show as installed?

Additionally, do you own any content through Steam, or just the base game?

Hello, this exact problem is happening to me. I also had content with epic that I once had played with and now it’s not available. I just got the new expansion with them with my epic rewards but can’t get it to work. It says I own it in the game but it’s not downloaded. I uninstalled and reinstalled epic launcher and uninstalled sims on Steam. In the epic, if I download sims it will only show epic content. If I download on Steam too, then the game won’t run. If I only install on Steam, epic picks up it’s there and shows installed but doesn’t download the dlc. 

when I go to the dlc page in the shop it only says in library and I don’t have the usual options like I do for other games in the epic library. I’m so lost 😞 

I figured it out! Leaving what worked in case this happened to anyone else. To download the content purchased from Epic when using another platform like Steam, you need to go into the EA app (not the website or game interface). Locate the sims 4 game then select manage add ons. You will be able to download your content there.
