I had that on Monday night. went to move our seats at T-24 because we decided we wanted aisle seats for a TATL trip and were grandfathered in to a window and middle....Made the change, clicked continue and then went back to look at the res to see if it really took. We were in the same seats but when I went to check in five minutes later, the res showed the original seats but the BP's showed the new seats. The best part, we each had our own row in E+ when it was all said and done.
