GPS wrong position

my location is placed randomly on the map and we are talking hundreds of km. Not possible to plan a trip since I’m not where

I am supposed to be. Restarting app and deleting/installing still does not fix this problem. Can’t rely on this app anymore and I’m on my vacation so it is as double problematic. All GPS settings in phone / car are on and app is working but occasionally for some periods it is happening what’s written above.
