Possibly a duplicate of this thread, but well, this service can’t find my street/house.
“Donauschwabenring” gives 0 results
“Donauschwabenring 34” gives 5 wrong results, but which are close
“Donauschwabenring 34, Mering” gives just Mering the town as result, which is unexpected and wrong in my opinion.
I would recommend changing the geocoder, because it can’t be that it doesn’t find “Augsburg Hbf” for example. This is just a basic thing. I know this sounds hard, but it just does not do the things it needs to do.
