They pushed it back at the last minute because of the rework in registration opt-in. Their disclaimer om the whole process was basically that it was a gift and came with no guarantees.
Thanks, so I'm not the only one who wondered what is going on. Their last message said literally: "You are still registered; there is nothing for you to do". Emphasis theirs, not mine. I didn't receive the December drop either. Their communication is confusing.
