when I first used the Kurviger (Pro) app on my tablet, the German map was visible.
Then I wanted to create a tour through the Czech Republic and downloaded the map. So far so good. It worked fine.
Now I want to plan a new tour in Germany, but where is the German map? I cannot find it.
Application allows to open multiple maps simultaneously and add more maps to the loaded ones, from where you downloaded them in device storage. Please have a look also in offline maps guide where more details are described.
and I think I found what happened: I didn´t add a new map, I opened it. So the map of Germany isn´t visible anymore but only the Czech map.
