@Suty hello !
Yes and it make sense but once you have uploaded it on computer, the display of kmz should be easier to acces on mobile app.
The only way for the moment is to go on internet app and "windy kmz" , click first link and then it open the kmz menu in windy app.
Why there is no button in the app to acces to it ?

Hello, I don't understand how to display my imported kml on my mobile (android).
It work well on browser version but I don't find on mobile.
Is it possible do display on mobile or is it only on browser ?
