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

Hi @santoso8118

It looks like the route simulation was enabled when in a tunnel. The simulation might be not accurate and when switching back to the real location near the tunnel some jumps can happen. Please note that you can disable simulation in tunnels by providing simulating: .never instead of simulating: .inTunnels when creating MapboxNavigationService.

Please provide a history file if you'd like to receive a more detailed look. Please take a look at this sample to check how you can record a history file.

@kried We are setting simulating: .never always and we never simulate user location. Is there any logic from Mapbox itself to start simulating location when user is in tunnel ?
