I have a reward booking and submitted a request to upgrade when I booked. I am not able to modify the upgrade request, the option to change booking is greyed out and when I try and select seats, it just spins on loading the seat map. Based on Cowtool, the upgrade has cleared but I can’t do much with the booking and I just want to select seats. Is this something that AC would need to look at? Any similar experiences would be appreciated.
