Currently Digitransit disruption info (GTFS-RT service-alert) handling is somewhat broken:
Disruption info is displayed sporadically and red triangles are not consistent
Red triangles disappear in some stages when searching for routes
Disruption info is hard to find especially on mobile as hover-texts do not work
Stop specific disruptions is only visible in "Disruption info" popup
Duplicate disruptions infos are shown in some cases
Currently data produced by HSL is incomplete but will be improved in the near future, for example trip cancellations and better service alert targeting will be implemented.
