there are 3 Bus Stops with the commonName of “Mitcham Fair Green”, which are fairly new - (a couple of years I think);
sms code 92171 stop “E” 490009949X
sms code 92172 stop “G” 490009949Y
sms code 92173 stop “D” 490009949Z
using the naptan code in
https://api.tfl.gov.uk/StopPoint/490009949Y/Arrivals
gives arrivals as does
https://api.tfl.gov.uk/StopPoint/490009949Z/Arrivals
but nothing for
https://api.tfl.gov.uk/StopPoint/490009949X/Arrivals
Bus Times app shows arrivals as does the Countdown at the stop.
I’m flummoxed. Whay am i not getting any data for 490009949X ?
