Using App as a SatNav

Hello.  I recently cycled from Dieppe to Mettmenstten, south of Zurich.  I used cycle.travel to create and adjust my route. I used my Garmin to navigate on the route BUT, my Garmin failed me!  I lost navigation.  I resorted to the Cycle.Travel app for navigation-it was brilliant (apart from I didn't take a handlebar phone holder-my mistake). To my point. Whilst following y route, the app continuously updated my position on the route as expected.  However, once the marker got to the edge of my phone, it went off screen and I had to manually move the map to see the next section.  Is there a setting that I'm missing so that the map automatically moves on screen to the show the next part of the route-much as a car SatNav does?

Thanks for any help.
