I confirm the problem. Public transit directions used to be working well in Vienna, Austria, and were very useful, as no other online tool or available printed timetable listing gathers and correlates all this information in one place. This looks like it has been deliberately turned off. Please restore it.
Now, when I try to get public transit directions, I get the following error message: "Your search for transit directions from ... to ... appears to be outside our current coverage area. Please consult our list of participating public transit agencies."
However, when I zoom on the map and check the bus, tram and ubahn stop icons, all the information is there.
