I have two Feature Layers added into a Map that I can see when I display the MapView. However, it's only the last added Feature Layer that can be processed by the Touch Listener. I cannot figure out how to make all Features Layers taken into account by the Touch Listener.
My goal is to differentiate a click on a CARTO_ETARE's feature from a click on a CARTO_PT_EAU's one.
Any help would be appreciated.
