Research direction

Start by reproducing the report with the provided Kotlin snippet on Android API 21 using Mapbox Navigation SDK 2.19.1. Trace how setNavigationRoutes handles the supplied route list and leg index, then verify that changing the index advances currentLegProgress and the driver's instruction.

Written by the indexing model from the issue text.

Description

Android API: 21
Mapbox Navigation SDK version: 2.19.1

Steps to trigger behavior
val currentIndex = routeProgress?.currentLegProgress?.legIndex

navigation?.setNavigationRoutes(
  listOf(currentRoute), currentIndex?.plus(1) ?: 0
)

This has been confirmed via a debug point that none of the values are null and setNavigationRoutes is called with the first parameter being a list that only contains the current route and the second parameter being 1 with currentIndex being 0.

Expected behavior

The navigation should advance to the next leg.

Actual behavior

It stays at the same leg - no changes to the current instruction for the driver.
