Why OSMAnd and Naviki.org can NOT route through this new tunnel in BIKE-mode? The take a 7km route to connect the both streets....
Any ideas? I really want to learn, why this happens...

Routing with OpenStreetMap.org (Graphhopper/OSRM) has no problem.
I tried to change the but no success until now...(or naviki don't use the maps directly and it will take some time?)
