In my case I got it Thursday afternoon. I was sitting outside and around 3 PM it was still in the same waiting mode that I had seen for a week. Hour later I went to look at my 15 ProMax again for something else and on the screen it said it was ready. Must have been downloading in background or the download was fast for playground and Genmoji.You got it because it’s obviously independent of the beta releases. You might have gotten it at 2am. Servers don’t sleep.
