seasons aren’t working

i’m new to the sims 4 and just downloaded seasons last week. i’ve been playing this whole week but the actual seasons have yet to show up. i have the new items in build and buy and cas, but the actual seasons themselves are nowhere to be found — no pop up or anything. ive done everything i’ve seen said on other posts like this: i’ve checked all my mods (removing them and clearing the cache), i’ve restarted my computer, and i’ve deleted and completely reinstalled the game. nothing works and i’m out of options. is there any way to fix this?
