Re: In game enabling not working
Update: This issue should now be fixed, as of the November 17 patch:
@DanielleOfRivia There's also a setting for Origin in-game within the Sims 4 Game Properties. (Open your Origin game library and right-click on the Sims 4 icon to see the option.) That needs to be enabled as well to use Origin in-game.
However, it's more reliable to buy packs through the Origin app or through origin.com. The in-game feature has been known to cause a couple of issues, including adding other packs to your order without your knowledge. So it might be better to use a different approach instead.
