Has anybody noticed problems with the seat-selection on BA Cityflyer flights? Since this morning, MMB isn't giving me the option to view the seating plan on flights to/from LCY... I can access my bookings and see my (previous) reserved seats, however can't change it or access the seat-map at all.

Paid or award booking, flights on E170 or E190, doesn't matter, it's all the same.
An no problems with mainline flight to/from LHR, for those bookings the button "View or change seats for this flight" is displayed (and working) fine.
Is it just me or is anyone else experiencing the same issue?
