Avios-24 is the most recent one from mid-May. I haven't gotten my Avios. Sent an email to Groupon and gave them the screenshots they asked for. After the time they said it would take to resolve it passed, I asked for a refund. Just sent in another refund request.
If AA redemptions ever came back I'd probably still want the Avios. But after being gone for so long I don't want to mess around with hoping they'll eventually come back.
I've done a lot of the 2K purchases, had this issue one time before. It was resolved within a week or two though with the Avios in my account.
