Just checked with Heathrow FBU and also the AFPEx people at Swanwick and there should have been no problem sending a DEP on your flight.
Our instructions on FIS are to pass all airborne times (wherever they have been filed) to Heathrow FBU for fpl activation. The FBU say they have been very busy but there have been no technical problems stopping them sending DEP messages.
If the FISO is unable to get through to the FBU the AFPEx team will happily send DEPs. They also report no system problems recently stopping them doing so.
I am back at work tomorrow and will check further but at the moment it seems like FISO / pilot / FBU / AFPEx misunderstanding.
Edit to add - If anybody else experiences problems getting London Info to activate your plan could you send me a pm with c/s, date, dep airfield and time and I will endevour to ascertain why.
