It seems that the northern and metropolitan are not giving back any information for the outbound sequence for the regular line.
Looks like it’s also affecting Piccadilly inbound, Metropolitan Inbound (only showing Watford --> Rickmansworth)
[edit: I believe both were showing correctly as of 2018-12-18 22:40, but incorrectly as of 2018-12-24 14:30]
Same result here in late March 19
We have this issue logged as SVC-6115 and it’s towards the top in our priority list of bugs so hopefully be fixed soonish. Thanks for your patience!
