Navigation starts off successfully

We go off route for some reason and apparently loose communication with Mapbox instructions
07Jul20-09:22:18 4000 INFO MyMapboxNavigationActivity$1.onOffRouteStateChanged : 254 => $$$ MAPBOX : ENTER : is offRoute = true

We go back on route but still have no apparent communication or limited communication with Mapbox instructions.
It also appears that several waypoints have been skipped in the process of coming back on route.

Steps to trigger behavior

Please see attached file for more detailed setup/options information
MAPBOX_BUG_SUBMISSION_07JUL20.txt

1. request a route with 25 waypoints
2. start navigating the route
3. the on/off/on route transitions start

Expected behavior

transition from on route to off route and back to on route should maintain the integrity of the original starting route and its waypoint content.

Actual behavior

going from on route to off route and then back to on route seems to break communication for navigation instructions and voice instructions and arrival event. Also when on route is again restored it appears to have skipped several waypoints in the original route requested.

Start with the attached MAPBOX_BUG_SUBMISSION_07JUL20.txt and the OffRouteObserver logs. Reproduce the route using 25 waypoints and the listed SDK components, then trace the on-route/off-route/on-route transitions. Done means the original route and waypoints remain intact and navigation, voice instructions, and arrival events continue working.
