Seat map not showing

We've got some G class tickets booked for November/December this year (LHR-JFK-ATL-MAN), but for some reason I can't see seat maps for either of the TATL legs. They're on the VS45 on the way out and the 110 on the way back. Any ideas what's going on?

Something similar happened to me recently, one of the delta legs had changed time very slightly, I needed to phone VS to confirm the change was ok and then was able to access again.

The same thing has happened to me, I believe it will show again when Virgin re-issue the ticket for the Delta flight but may take some time as the date is further away.

Similar when I had my flight changed.
I called flying club and they said they could assign my seat, anything but the seats we wanted 6A &K
I booked row 7 then got a call 1/2 an hour later to say they had got row six available and did I want them.
Yes please, and thank you.
Brilliant service and well worth a call.

Just had the same for an upcoming flight that was caused by a change to the return flight. Quick call to FC and they reset the seat map. About ten minutes later all good again
