My CC miles posted this morning with 0 loyalty points for 2024 year for purchases that were made after 3/1 so yeah.
Some of the travel blog sites have picked up on it and lots of chatter on Reddit as well about it so looks like it's everyone. They did say it might take 8-10 weeks to get the loyalty points posted correctly. Amazing that they have to do it this way when a simple line of code could have handled the update... now they get to deal with all of complaints, phone calls, and bad press.
