Hi, I have an issue wit offline map usage when I am out of signal. Despite I have the whole country downloaded, sometimes I get the map only partially displayed on the screen. It happens zooming in and out or moving around, then it may get back.
Again, I am sure I have the whole country downloaded but sometimes, in condition of no signal or minimal signal, I get part of the map disappeared.

Am I doing or assuming something wrong? any solution? In the pic you have a screenshot example of it
