I know I'm late but ... did you end up buying it here or on the Unity Asset Store? I'm curious about the same thing ...
I got it here sadly, that is why I made the question and I didn't want to pay it again on the Asset Store. Sadly never got a reply and at this point I don't care anymore really. If you are going to buy do it directly on the asset store as it seems the most updated according to the asset store (december 2021 vs january 2021)
