I hope someone here can help as the OSMAND site is not user friendly.

I am planning a trip to USA and will be driving from Niagara Falls to the west coast following Route 66.

I have downloaded all the required maps both onto my android smart phone (Moto 5E Play) as well as my Samsung TAB A, a total of 15 USA and Canada files.

Twice now I have tried to test a GPX file only to find that the downloaded maps are no-longer available meaning I need to download them again. These files are quite large and they really eat into my download allowance.

This is now the second time this has happened and it will be a PITA if it happens while doing this drive so if anyone has any ideas what is happening, it would be greatly appreciated.

Regards
Bob
