Glad I found this thread to find that I'm not alone.

Up until January, I was getting AA points for Hyatt stays.

Then it stopped. I've had three stays since then where I should be getting miles, but nothing has posted. I contacted both the Twitter team and my concierge, and they both don't even seem to be aware of this program.

Seems like an uphill battle. Are people having better results from the AA side?
