After creating a route a black banner appears that lets you download the directions. This actually does download an offline map, but it’s formatted to fit the route.
This works with my old LG Rebel 4 phone but not the new Rebel 4. Both are Android 8. It also works on my Android 10 tablet.
But the black banner just does not appear on the new phone, therefore you can’t save the directions/map. Settings appear to be the same on both phones.
Any idea what might enable the black banner to appear?
