Description

Mapbox Navigation SDK version

1.3

Steps to reproduce

There is an issue with lane guidance not being shown properly. This is coming from the Nexar app. Using the navigation in the app, there are times when lane guidance isn't showing and other times it is. The biggest one is on I-595 in Ft Lauderdale on the western end of the interstate, where it merges with I-75 and the Sawgrass Expressway. Lane guidance is missing for a 6 lane exit in 3 directions.

Expected behavior

The end user should be directed to stay within the proper lane for routing to the destination they are going to. The instructions should tell the end user to "exit right using the right two lanes" or "continue straight using the 3 center lanes" instead of disregarding that intersection and giving instructions on the next intersection down.

Actual behavior

Lane guidance is not showing up, especially in complicated lane guidance intersections.

Is this a one-time issue or a repeatable issue?
