Also still works for me. I have $5,000 (A) and $5,005 (B) purchases this last week which posted today. I got 2x small biz points on the fee for (B), and 2x small biz points on the "payload" for (A) so far. I'm guessing the others will follow.

On the $5,000 for (A) I've also gotten the 1.5x for the biz plat > 1.5x, and the 5k bonus for $5,000+ purchases (might have been targeted), for a cool 3.5x ^

ETA: All expected bonuses posted, with the exception of 125 points for the 2x small biz for the fee part of (A) only. Weird, but works for me.
