If I choose to drive on anything except the freeway, I get told the road is closed, drive it anyway (the road is, after all, not closed) and spend the entire journey with a mapless screen. Great 4G+ reception the whole way. Happens all over NSW. Weird.
If you were interested in trying another app, I love Waze and find its directions and navigation far superior to Google Maps (even though it’s owned by Google, go figure).
If you don’t mind trying a map app based on OSM, try Magic Earth. It has really good navigation for driving and you can even download large maps offline for a fraction of the storage it would take using Google or Apple.
Google bought Waze just to keep it out of anyone else’s hands. They’ve mostly ignored it after that.
They have integrated some of the crowd reporting stuff over to Maps. But that’s it.
