In line with my experience, tried it to plan a route around northern France this summer and it got stuck a couple of times. Essentially, it tried to route me back to a position earlier in the route and would not recalculate, resulting in me going in a circle twice. Especially annoying if you are on the motorbike and cannot just restart the navigation mid-ride. Switched to the openstreetmap app, their navigation never did such a thing to me. Very weird since the projects seem to be somehow related
