That particular version used to work great with Android 9 on my S9. However with Android 10, I have one issue - when screen is off (even if Navigon set to work in the background), it will lose gps signal when not in the foreground. When you open app again it will search for gps signal and update your location.... not sure if there's any solution to it. I guess, all great things come to their end.
Cheers,
