Bought Scriv 1 Three Weeks ago but have to pay $25 to upgrade?

According to … or-windows “The update to Scrivener 3 is free for users who bought Scrivener 1 on or after 20th November 2017.”

I bought Scrivener 1 three weeks ago and yet I have to pay $25 to upgrade to Scriv 3? I tried to upgrade in Scriv 1 but it’s saying that I get a “discount” and still have to pay to upgrade.

So, had I waited three weeks, I could have bought Scriv 3 for $50, but now I have to pay $75?

If that’s the case, then please issue me a refund all together and I’ll find another writing software to use.
