I’ve noticed that bus stops retrieved using the StopPoint API sometimes have interchanges to the Elizabeth line flagged up, and sometimes they don’t.
This is very counter-intuitive, and seems to impact the TfL web site as well as just the API.
For example, whilst stop F at Liverpool Street Station has an Elizabeth line interchange, stop B at Moorgate station does not, which of course is clearly incorrect. Abbey Wood and Woolwich also have named “station” stops which don’t have the interchange correct.
