Apparently, ApplePay was working last week at RiteAid and CVS Pharmacies. However, over the weekend, they both decided to disable ApplePay on their systems. No reason was given for the move. However, it was suggested that it was because they were both throwing their support behind a rival system being developed by a Merchants' Association. Here is the link to the story on Daily Finance:
