Niether OSMAnd nor Navfree lists my town and several others in Massachusetts. Is there a reason for this? How can I navigate to and from my home? I can see the streets on the maps. But I can’t search addresses because the town isn’t listed I can see my street it isn’t labeled either. My town is Boylston. A few other towns are missing in the search too.
In Osmand press Search>Search address tab>Choose region (Massachusetts)>Choose city. Type and if Osmand does not show the city you searched for press “Search Villages/Postcode”. I can find 1 Boylston. Hope it is yours 
If not see if you can find it in OSM. If it’s not there Osmand will not find it.
