I complained before that they had slightly broken the route planning....
well now they have completely broken it! The map shows a blue line which
wanders from start to finish without particularly matching any roads.... and
whereas the itinerary used to list road names (with a fair number of
errors), now it gives

Turn LEFT (West) onto Local road(s) 0.6 mi
Turn RIGHT (North) onto Local road(s) 0.1 mi
Turn LEFT (West) onto Local road(s) 0.5 mi
Bear LEFT (West) onto Local road(s) 0.1 mi
Bear LEFT (West) onto Local road(s) 0.1 mi
Turn LEFT (South) onto Local road(s) 0.2 mi
Bear RIGHT (South-West) onto Local road(s)
