Sorry, I thought I had translated...
Today I went out for a ride, I had prepared an itinerary at home, which I synchronized with the app, I stop to eat, I stop browsing, when I finish eating, I'm about to leave, I restart the route and the app tells me IMPOSSIBLE TO CALCULATE THE ROUTE... It was an area where there was no phone signal, I also tried to activate offline navigation, I downloaded all the maps of Italy, shouldn't it browse even if there is no phone signal and data? I'll leave you some screenshots...
