Mapbox with Walking profile doesn't draw route on pedestrian path if user is located on the Main street (i.e. Driving path)

Android API: 29
Mapbox Maps SDK version: 9.6.1
Mapbox Navigation UI SDK version: 1.5.1

I was exploring MapBox Direction API using Walking profile and experienced the following issue

In direction API, if my start location is located on main street, then route is drawn on the main street. I have configured my code with Walking profile hence my route should not be drawn on main street at any cost, as route should always be drawn according to nearest pedestrian path.

I checked above scenario in Google and found working as expected. Please let me know if this is a bug in MapBox Direction API or am I missing any configuration in my code?

Steps to trigger behavior

1. User's current location is on main street rather than on sidewalk.
2. Using Mapbox Walking profile, the route shall be drawn including sidewalk and crosswalk for user's safety

Location - Chicago, USA

Case 1: If start & destination coordinate is on main street and not on Sidewalk
Start Coordinate - 41.90084455967382, -87.6232866902274
Destination Coordinate - 41.900860585647926, -87.6252983194398

Case 2: If start coordinate is on main street & destination coordinate is on Sidewalk
Note: Snapshot attached is of this case
Start Coordinate - 41.90084455967382, -87.6232866902274
Destination Coordinate - 41.90086457822011, -87.62527686154802

val walking: WalkingOptions = WalkingOptions.builder().alleyBias(1.0).walkwayBias(1.0).build()

mapboxNavigation.requestRoutes(

Expected behavior

If the route is fetched using Mapbox Walking profile, then routes shall be drawn on the pedestrian path.

Actual behavior

Route is not drawn on sidewalk if start and destination location is present on main street.

Parti dalla chiamata a mapboxNavigation.requestRoutes e dalla relativa configurazione di WalkingOptions, quindi riproduci entrambi i casi di coordinate con le versioni dell’SDK specificate. Ispeziona la geometria del percorso restituito e confronta dove passa rispetto ai percorsi pedonali; l’issue è risolta solo se i percorsi a piedi usano il percorso pedonale appropriato quando il punto di partenza si trova sulla strada principale.
