Why am I missing the functions of the ACNH update 1.5.0?

I downloaded the update for ACNH and also got the letter from Nintendo, but I'm missing the new functions (new skin colors, pumpkins etc.) I was also looking for an error message are you the same and how can I fix the problem?

If you had checked out the Nintendo website, you would know that these are all things that will be available in October. Is it October already? No. ; )

As someone wrote, it will only be available from October… Please read first about the updates ^^ Only people who reel have the "pleasure" now.
