I used a short trip and map matching shows an incorrect result. Tried with Graphhopper map matching on my local computer as well as official API(https://graphhopper.com/api/1/match?).
I also tested using the Graphhopper routing and used this trip’s start and end location for a path search. The result is fine. So OSM data should be intact in the area.
Anyone knows what happened for the map matching?
