I've downloaded a bunch of custom content off TheSimsResource and none of it will show up in my game. The mods message in the beginning doesn't show up, it's not in my Options>Other>View Custom Content, it's also not in my CAS. I have mods enabled and they're all downloaded as PACKAGE files in my Mods folder. I can't figure out what the issue is!

Apparently the game does not use the folder you think.
Here is an easy way to find out which folder your game is using: https://sims4.crinrict.com/en/2018/07/how-to-find-your-user-folder

My PC doesn't have OneDrive or iCloud set up. Tried a bunch of their fixes, none worked. Thank you, though!

Did you find the folder the game uses following the linked advice?

I didn't, but I figured out a solution on my own! I deleted the Mods folder and the game created a new one that I can actually use now. Thank you for your help, though!
