Cannot access MMB after upgrading a flight leg

[Oliver]

I have a BA Holidays booking that departs next week. Some CW reward seats were released yesterday, so I called BA and got them (thanks SeatSpy).

However, ever since BA made the change, I cannot get into Manage My Booking. Whenever I try to access it, a message says “Error – There was a problem with your request, please try again later”.

Any idea whether this might resolve on its own? It has now been almost 36h.

I have got the same issue: did you manage to get it resolved?
