Unable to download expansion pack sims 4

After purchasing a pack and add-ons for The Sims 4, I tried to download them, but I keep getting an error message saying “There’s a problem with the download. Please try again in a few minutes.” It has been stuck like this for several days. The download seems to be stuck somewhere, on one hand there is an option to Download, but on the other hand it says the content is already installed, yet it doesn’t appear in the game. I’ve already tried everything, but unfortunately nothing works.
